Jim Parsons Reprises Big Bang’s Sheldon Ahead of Young Sheldon Series Finale — Watch Video

Young and Old Sheldon join forces in an epic new video ahead of Young Sheldon’s series finale.

In a TikTok promoting the Big Bang Theory prequel’s arrival on the video platform, series star Iain Armitage tries out a “new filter,” with an assist from Jim Parsons.

“So, apparently there’s a new filter that shows you what it looks like when you grow up,” Armitage says. “I don’t know how accurate it is going to be, but let me try it out.”

Then, upon tapping his screen, Parsons appears to assess the results. “Hmm, I’m not sure about this,” he says, before acknowledging that he and his 14-year-old counterpart sound nothing alike: “Oh! It changes your voice, too… I don’t like it!”

As previously reported, Parsons, along with Mayim Bialik, will reprise their roles as Drs. Sheldon Cooper and Amy Farrah Fowler in Young Sheldon’s series finale, airing Thursday, May 16 (CBS, 8/7c) — exactly five years to the day since Big Bang signed off in 2019. This will mark the first time that Parsons and Bialik have appeared together on Young Sheldon, and the first time that anyone from Big Bang will appear in person, on screen, on the wildly successful spinoff.

Parsons, who is an executive producer on Young Sheldon, has served as narrator on all seven seasons, while Bialik has reprised Amy and served as co-narrator on two episodes.

Storyline details surrounding their return are being kept under wraps.

Young Sheldon, which stars Armitage as the future theoretical physicist, is told from the perspective of a more mature Sheldon, who is older than the version we last saw on Big Bang. Through his narration, we’ve learned that Sheldon and Amy go on to have multiple children — including a son named after Sheldon’s best friend, Leonard Hofstadter.

The prequel will be followed by a second Big Bang offshoot centered on Sheldon’s older brother Georgie (played by Montana Jordan) and his new wife Mandy (Emily Osment), which is slated to premiere on CBS during the 2024-25 TV season. Series co-creator Chuck Lorre is also working on a third Big Bang Theory series — a top-secret project “derived from” the CBS mega-hit that is earmarked for streaming service Max.
