Young Sheldon cast now: See what the sitcom stars have been up to since the spinoff wrapped

Iain Armitage (Sheldon Cooper)

Iain Armitage portrays the quirky, rule-following supergenius Sheldon Cooper as he struggles to fit in as a disproportionately young high school — and, eventually, college — student.

The young actor had to…in front of Parsons and series co-creators …during his audition. Armitage said…which helped him land the part.

“No one’s really the same when they’re a grown up as they are when they’re a kid so I can sort of do my own thing,” Armitage …“Once you understand the character of Sheldon, then voila!”

Armitage first caught attention with his YouTube series, Iain Loves Theatre. As his channel gained notoriety, he got to be a…correspondent at the… at just 6 years old. Not long afterward, the young theater fanatic landed a key role on Emmy-winning series …(2017–2019) as Ziggy, the son of single mother Jane…He also appeared on a 2018 episode of The Big Bang Theory in a video Sheldon recorded when he was, well, young Sheldon.

While managing the workload of his full-time sitcom gig, Armitage has also taken voice acting jobs, including as a younger (but still perpetually hungry, goofy, and chill) Shaggy in Scoob! (2020), and as the protagonist in Paw Patrol: The Movie (2021).

The 16-year-old star hasn’t appeared in any projects since Young Sheldon wrapped, but it’s safe to say his future looks bright.

Lance Barber (George Cooper Sr.)

Lance Barber plays Sheldon’s football coach father, George Sr., who is a complete contrast to his bookish son.

Barber’s breakthrough came in HBO’s acclaimed comedy… (2015–2014) as the chief tormentor of…Valerie. He’s been a small-screen regular ever since, including a recurring gig as suicidal dirtbag Bill Ponderosa in…(2010–2018) and guest spots on…

Barber’s introduction to the Big Bang universe came in the original series, when he played Leonard’s… high school bully. In a… he said he hoped fans would forgive the slight canonical disruption: “I think that we’ll have to ask the fans of the show to suspend some disbelief. Based on social media, it’s going to be difficult for some of them and I hope that I can do a good enough job to take them away from that.”

In 2025, the actor reprised the role of George Sr. in an episode of Georgie & Mandy’s First Marriage.

Barber’s wife, Aliza, is a chef. The couple shares two children.

Zoe Perry (Mary Cooper)

Zoe Perry portrays Sheldon’s empathetic and religious mother, Mary Cooper, who is able to get through to him in a way that doesn’t come quite as naturally for the rest of the family.

Perry’s first TV appearance came before her 10th birthday when she portrayed a younger version of Jackie — a role played by her mother, Oscar-nominated actress…(1992–1995). She began a proper acting career about a decade later, booking appearances on…(2017).

In Young Sheldon, Perry once again plays a younger version of her real-life mother, given that Metcalf was Mary Cooper on The Big Bang Theory.

“I definitely never imagined I’d be playing my mother at a younger age. I feel very privileged that it’s happened and that I get to do it,” Perry…“I definitely called her up as soon as I knew that there was an audition in place… Her really great advice was just that, you know, the comedy’s there obviously… As long as you ground it in reality, you’re golden.”

Since Young Sheldon ended in 2024, she’s reprised her character on the spinoff, Georgie & Mandy’s First Marriage. The actress also appeared on The Conners in 2025.

Perry has been married to Canadian film producer Gab Taraboulsy…

Montana Jordan (Georgie Cooper)

Montana Jordan plays Sheldon’s less intelligent younger brother, Georgie, who’s obsessed with scheming, making money, playing football, and chasing girls.

The native Texan has a short résumé, mainly because playing Georgie became something of a permanent profession. Toward the end of Young Sheldon, Georgie meets and subsequently marries Mandy . The couple was so popular that they landed a spinoff, Georgie & Mandy’s First Marriage (2024–present).

His only other role — and the first one he filmed — came courtesy of fellow southerner Jody Hill, creator of…(2009–2013) and…(2016–2017). In Hill’s film The Legacy of a Whitetail Deer Hunter (2018), Jordan played ….young son as they set out on their first hunting trip together. The gig landed Jordan a manager, who sent him to audition for Young Sheldon.

“I felt like it really fit, like, me in real life, so I went ahead and just went for it,”…“I sent in a self-tape because I was in Texas at the time and I went into L.A. for the first audition and I was the only kid there so I ended up getting it.”

In 2025, the actor…with whom he has a daughter.

Annie Potts (Meemaw)

…portrays the hard-nosed, straight-shooting Meemaw, Sheldon’s grandmother, who keeps the family in check.

In a 2017… ahead of the show’s premiere, the veteran character actor gave credit to the original series: “All of us are benefitting from, you know, how beloved the show is in general, and Jim Parsons is in particular. We’ll all be sailing on those luxurious coat tails.”

Potts came in as the most accomplished member of the regular cast. Her career dates back to 1978, where her performance in…(1978), opposite… earned her a Golden Globe nod.

She was a big-screen regular for years, landing supporting parts in… (1986), Crimes of Passion (1984), and Jumpin’ Jack Flash (1986). Then, of course, there’s her most famous movie role: secretary Janine Melnitz in…(1984), a character she’s since reprised in three sequels.

Around that time, however, she became an even bigger star on the small screen. She was interior designer Mary Jo Shively in the long-running hit…(1986–1993) and went right into another sitcom, Love & War (1993–1995), which landed her an Emmy nomination. She later earned two SAG nominations for the drama Any Day Now (1998–2002).

Many viewers, of course, will recognize her as the voice of strong-willed shepherd… franchise.

Potts is married to…and has three children, including one from a previous marriage.

Raegan Revord (Missy Cooper)

Raegan Revord plays Sheldon’s socially (if not intellectually) gifted twin sister, Missy Cooper. The two sometimes butt heads but ultimately remain very close.

The young actress said she secured the role by nailing the Texas accent. “I was living in L.A. whenever I got the audition and so I went in tons of times,” Revord…“One night we got an email and they were like ‘Hey, can you learn it with a Texas accent?’ and I was like, ‘Okay, I got this.” And then I went in the next day and I did it and then I got it.”

When she was 6, Revord debuted as Lily’s friend Megan — where she memorably says blue and yellow make “blellow” — in two episodes of…(2014–2016). Her comedy experience has extended to…(2015), and Alexa & Katie (2019). In 2024, she reprised her role as Missy on Georgie & Mandy’s First Marriage.

Revord is also an author. She wrote the 2025…Rules for Fake Girlfriends and hosts the Instagram book club Read with Raegan, which has over 159,000 followers.

Matt Hobby (Pastor Jeff)

Since Sheldon grows up in a devout Christian family, the church plays an important role in the show. That fact helped actor Matt Hobby, who plays Pastor Jeff Difford, get elevated to the main cast in season 3.

Before appearing on the hit sitcom, he booked roles on a handful of other high-profile series, including five episodes of… (2012), 10 episodes o…(2013–2015), and five appearances on… (2015–2016).

Young Sheldon remains Hobby’s longest-running gig, which made the 2024 series finale all the more emotional. The actor posted a tribute to his time on the show…showing photos from the beginning and the end: “My first day at Young Sheldon, and my last day at Young Sheldon. I’m so grateful to have been a part of this wonderful story for 7 years. I will miss these kind, genius, loving people. I’m so proud that this will always be a part of my life. #youngsheldon.”

Hobby is married to actress Mary Grill, who plays Pastor Jeff’s eventual wife on the show. They have three children together.

Emily Osment (Mandy McAllister)

Emily Osment joined the show in season 5. Her character, Mandy, shows up at Georgie’s laundromat, and the two make a date that eventually leads to marriage.

Osment is currently continuing the role in Georgie & Mandy’s First Marriage. Speaking… she admitted she was surprised to see a non-Big Bang audience discover her character on Young Sheldon: “It’s like we have these young preteen kids coming in to watch these shows that didn’t know there was an entire origin story before it, and I think it goes to show that these shows do live on their own page, and they have a life to themselves, and the audience will find it.”

Osment began her career as a child actress, notably as the villainous Gerti Giggles in… (2002) and… (2003). She’s arguably still best known as Miley’s best friend Lilly Truscott on…(2006–2011).

The actress had the starring role as a personal chef in the sitcom…(2014–2018), earning three Teen Choice Award nominations, and was part of the SAG-nominated cast of…(2018–2021), alongside Oscar winner…

Osment married musician Jack Anthony in 2024, but the two… five months later. She is also the younger sister of Oscar-nominated actor…

Wyatt McClure (Billy Sparks)

Wyatt McClure plays Sheldon’s original nemesis and neighborhood bully, Billy Sparks, although he becomes friendlier as the series progresses.

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

The young actor is still padding out his CV, landing small roles in the boxing drama Glass Jaw (2018), the twisty…led thriller I See You (2019), and two episodes of The Santa Clauses (2023).

McClure has also dipped his toes in stand-up comedy, having performed at the Hollywood Improv and elsewhere around L.A.

Jim Parsons (Old Sheldon)

Jim Parsons reprises his signature role as Young Sheldon’s narrator, often introducing and closing episodes. He also appears as a post-Big Bang Theory Sheldon in this prequel’s series finale.

Parsons began his career with minor parts in… indie darling …(2004), the… (2006), and… (2004–2005). Then came the role that defines him to this day. Parsons rose to A-list status as eccentric, overbearing genius Sheldon Cooper and won four Emmys for the role.

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

During Big Bang’s 12-year run, Parsons squeezed in several films, including a scene-stealing musical cameo in The Muppets (2011), the lead voice role of a misfit alien alongsid…(2015), and a supporting part in the inspiring, Oscar-nominated…(2016). He also earned an Emmy nomination for HBO’s…2014), reprising a role he played on Broadway in 2011.

Parsons earned another Emmy nomination for… miniseries Hollywood (2020), prosecuted Ted Bundy in…(2019), and headlined the drama Spoiler Alert (2023).
