Young Sheldon Character Ages vs Their Real-Life Actor Counterparts

With the expanding The Big Bang Theory franchise, there are questions about how old George is in young sheldon  and how that works for the sequel series. Young Sheldon is set in the 1980s, making it sometimes difficult to determine the ages of the characters. With many of the key characters in the show having already appeared as older versions in The Big Bang Theory, it added to the confusion, which will get even worse with the new upcoming series Georgie & Mandy’s First Marriage.

As a child, Sheldon is surrounded by his family, neighbors, and friends, whose actors also needed to be able to demonstrate their character’s frustrations with the child prodigy, while still showing him adequate affection. Some of these characters have made an appearance on TBBT, such as Mary, Missy, and George Jr., so it’s intriguing to see the lives they led that shaped them. Young Sheldon begins when Sheldon is in his first year of high school, chronicling his life as he moves into college as a teenager with…along for the ride.

George Cooper Jr. – Age 18

Actor Montana Jordan – Age 20

George Jr. (Georgie) is the oldest child in the Cooper family. He is different from Sheldon in every way, behaving like a typical, slightly rebellious, teenage boy. Georgie is 14 years old in Young Sheldon season 1, starting his freshman year alongside his 9-year-old brother, and 18 years old in season 6. Georgie goes through quite the arc, seeing his child born in season 6.

While he can be mean to Sheldon, he has a good heart and would ultimately do anything to protect him. Georgie appeared twice on The Big Bang Theory in seasons 11 and 12, being 42 in his first appearance and 43 in his second.

Georgie is played perfectly by 20-year-old Montana Jordan. He is slightly older than the character, which may give him an edge in doing Georgie’s complexities justice. Of the cast, he is the only natural-born Texan .so his accent is genuine. Before starring in Young Sheldon, Jordan appeared in The Legacy of a Whitetail Deer Hunter, in which he played Jaden Furgeson. He also played young Georgie in an episode of TBBT. In terms of playing Georgie, Jordan had this to say.“When I first read the role of Georgie, I thought I was reading an autobiography. Everything lined up to my life back in Texas.”

Missy Cooper – 13 Years Old

Raegan Revord – 15 Years Old

Missy is Sheldon’s twin sister. Despite having shared a womb, Missy and Sheldon are complete opposites. She has no interest in academics and struggles through school, but she has a social intelligence that Sheldon could only dream of. Her snarky personality and undeniable street smarts make her one of the funniest characters on Young Sheldon. Missy is 9 years old in Young Sheldon season 1 and 13 years old in season 6. Missy was 27 when…season 1 and was played by actress Courtney Henggeler.

15-year-old Raegan Revord of the Young Sheldon cast is a California-born actress who has spent her life performingMissy is her first major role, but she handles it with maturity beyond her years and has also had small roles on Grace & Frankie and Modern Family. Her performance as the snarky Missy just shows that she has a great career ahead of her. In terms of playing the sassy Missy Cooper, Revord comments that she’s actually quite different from her character

“Im actually very different from Missy. Im way more introverted and nerdier. Missy has so much confidence and I really admire her for that.”

Constance Tucker – 70 Years Old

Annie Potts – 71 Years Old

Constance (also known as Connie or Meemaw) is Sheldon’s maternal grandmother and a very special figure in his life, even through The Big Bang Theory. As an adult, Sheldon has criticisms for every member of his family, but in his eyes, Meemaw is perfect. Connie is 66 years old in Young Sheldon season 1 and 70 years old in season 6. Meemaw is also in an episode of The Big Bang Theory in season 9 after countless references are made toward her on the show, during which time she is 93 years old and played by actress June Squibb.

71-year-old actress Annie Potts has had an impressive acting career, with roles in Ghostbusters and Pretty in Pink. Her very first role on the screen was back in 1977, alongside Dick O’Neill in Hollywood High. She voiced Bo Peep in Toy Story 4 and reprised her role as Janine in Ghostbusters: Afterlife. Potts has reportedly had tons of fun with playing Sheldon’s precious Meemaw and even got her inspiration for the character from a surprising source, saying.

“Ive sort of imagined her (like) Dolly Parton in Steel Magnolias, which came out in 1989. I think that Meemaw probably admired Dolly.

Mary Cooper – 43 Years Old

Zoe Perry – 40 Years Old

Mary Cooper is Sheldon’s mother, who does her very best to raise such a precocious child. She is often at a loss about what to do with him, but it is clear in every episode that she adores her son very much. Mary is 39 years old in Young Sheldon season 1 and 43 in season 6. Mary Cooper had a surprisingly large role in The Big Bang Theory, first appearing in season 1’s “The Luminous Fish Effect”, when her character would’ve been around 57 years old and her final appearance in season 11 is 67, though she certainly looked far from it.

Mary is portrayed by actress Zoe Perry, who is currently three years younger than her character. She does a remarkable job at imitating the speech and behaviors of the actress who played Mary in TBBT, likely because that actress is her mother, Laurie Metcalf. Perry has appeared on Scandal and NCIS. Perry commented on the ease of taking over the role of Mary Cooper from her mother in an interview with … saying,

“Genetics definitely played a very helpful part in this portrayal because I didnt have to really think about mimicking my mom as Mary its just part of who I am, to an extent.”

George Cooper Sr. – 49 Years Old

Lance Barber – 49 Years Old

George Sr. is a well-meaning father who often misses the mark. He faces a lot of pressure to take care of his family and support his wife, who takes on too much pressure herself. George is 45 years old in Young Sheldon season 1, and 49 years old in season 6, which is only a year shy of the age that audiences know he will pass away (another serious issue that Young Sheldon will soon explore)….in the series, but Young Sheldon hasn’t shown it onscreen. He’s passed away by the time The Big Bang Theory rolls around.

George is played by Lance Barber, who is currently the same age as the character. Lance Barber is recognizable due to roles on It’s Always Sunny in Philadelphia, Gangster Squad, and For Your Consideration. George being different from how he’s talked about on TBBT is a hot topic among viewers. Barber told …that his role as George was left wide open for him to interpret:

“There was a little backstory but it wasnt deep. It was just set-ups and punchlines for jokes about Sheldons past, and what they painted was almost a cartoonish character. They left open a lot of room to discover more.”

Dr. John Sturgis – 72 Years Old

Wallace Shawn – 80 Years Old

John is 68 years old in Young Sheldon season 1 and 72 years old in season 6. A college professor and fellow genius, he is often regarded as the old version of Sheldon, as they both lack common social skills. He is an important friend to Sheldon and was even in a relationship with Meemaw. Sturgis is also considerably sweeter and more bubbly than Sheldon, referred to by Meemaw as a “teddy bear.” Professor Sturgis isn’t in The Big Bang Theory and isn’t mentioned either, despite being something of a mentor to him.

Dr. Sturgis is played by Wallace Shawn, who is nine years older than his character. He started acting late in life, but quickly gained traction, earning fame for his roles in films like The Princess Bride. He also does a lot of voice work, with the actor becoming notorious for voicing Rex in the Toy Story franchise. He’s also lent his voice for The Simpsons, King of the Hill, Star Trek: Deep Space Nine, and The Incredibles. He recently appeared on the TV show Evil as Father Frank Ignatius

Tam Nguyen – 19 Years Old

Ryan Phuong – 21 Years Old

Tam is Sheldon’s first friend in high school, most likely due to the fact that he has an equally difficult time making friends. He’s much closer in age to Georgie, as Tam is 15 years old in Young Sheldon season 1 and 19 years old in season 6. His family emigrated to America from Vietnam, and he has witnessed a great deal of trauma in his life, which sometimes results in outbursts. Tam does appear in one episode of The Big Bang Theory season 12, during which he is 44 years old and played by actor Robert Wu.

Tam is played by Ryan Phuong in Young Sheldon, who is two years older than his character. If fans take a look at … they will also be able to see that he is an avid dancer as well. Young Sheldon is Phuong’s big break, but he has had small roles on The Thundermans, Shameless, and The AXI: The Avengers of Extreme Illusions. He also has used his dance skills to appear as a dancer in the video game Just Dance Kids 2.

Brenda Sparks – Age Unknown

Melissa Peterman – 50 Years Old

Brenda is the blunt and down-to-earth neighbor to the Coopers. At the start of the series, she is rough around the edges and will often mock Mary and her family. However, as time goes on, she shows more signs of compassion. She has developed an attraction to George, who has returned those feelings, possibly leading to the infamous affair that audiences knew about before the start of the show. It is unclear how old Brenda is, but she is likely close in age to the actress that plays her, Melissa Peterman.

Peterman is 51 years old and is best known for her role as… Peterman has had a long career, first appearing in Fargo. She’s also had roles in Here Comes the Boom, Pretty the Series, Baby Daddy, and most recently appeared in The Hammer. Brenda isn’t seen or mentioned in The Big Bang Theory, but it is alluded to in Young Sheldon that she’s the woman George ends up having an affair with. However, season 6 may have made the George affair situation all the more complicated.

Billy Sparks – 13 Years Old

Wyatt McClure – 14 Years Old

Billy 9 years old in Young Sheldon season 1 and 13 years old in season 6. Brenda’s son, he is a constant bully to Sheldon, who even talked about Billy in his adulthood on TBBT. While Billy loves to torture Sheldon, he has expressed feelings for Missy. Fans have theorized that Billy could end up being Missy’s infamous ex-husband. Though he’s never seen in The Big Bang Theory, Billy is mentioned several times over the course of the series, including that he put a peso up Sheldon’s nose and broke his collarbone on the playground.

Billy may not seem as intelligent as the other characters on the show, but the same cannot be said for 14-year-old Wyatt McClure, who portrays him. If fans of the show take a look on…they’ll see that McClure has a talent for stand-up comedy and has done a number of shows. He has also appeared in a few other roles, such as in the films Psychos, Glass Jaw, and Terror of Hallow’s Eve. In an interview with…Wyatt said of his character Billy:

“I was supposed to be a bully, however, I think they saw me and changed my character to a silly, fun kid.”

Sheldon Cooper – 13 Years Old

Iain Armitage – 14 Years Old

Sheldon is the titular character of Young Sheldon that audiences already knew and loved from TBBT. Sheldon is one of the smartest child geniuses on TV, and the search to find a young actor to follow up Jim Parsons’ portrayal could not have been easy. Sheldon is 9 years old in Young Sheldon season 1 when he starts high school as a freshman with his older brother Georgie. In season 6 Sheldon is in college, and Sheldon is 13 years old in Young Sheldon season 6. Iain Armitage is 14-years-old, which makes his fantastic performance even more impressive.

He also grew up in a theatre-loving family, and showed skill as an actor from an even younger age. He’s appeared in Big Little Lies as Ziggy Chapman, Scoob!, and The Glass Castle. TBBT actor Jim Parsons was floored by Iain Armitage’s audition .

“Watching Iain bring this young version of this character to life that Ive been working on for a decade of my own life, it was really moving, I felt such a sympathy for this little guy. It was kind of mind-blowing to see him brought to life through Iain.”

Armitage certainly adds a new spin on the character, making Young Sheldon entirely his own show.

How The Age Differences Played A Part In The Show’s Storytelling

The Young Sheldon cast keeps the age differences quite small compared to other TV shows, so it doesn’t impact the storytelling too much. However, there is one particular case in which it does and that is with Sheldon’s older brother, Georgie. Georgie’s romances in Young Sheldon were always a smaller part of the series until there was the introduction of his girlfriend Mandy. Though this became one of the main relationships in the series, it was also the most problematic, as George was 17 when he met the 29-year-old Mandy.

The two ended up having a child together and got married which led to their… The age gap between them plays into the story, but the off-putting aspects of the relationship are glossed over for the most part. However, it would likely have been even more controversial had it not been for the slight age difference between George as a character and the actor Montana Jordan.

Jordan was 19 when Georgie was 17 which helped ever so slightly with the cringey elements of the story and was essential for making Georgie and Mandy last. Had he been the same age as Georgie, with Mandy’s actor Emily Osment being 30 at the time, it would have further highlighted how creepy the relationship really was.
