When Parsons appeared on The Tonight Show Starring Jimmy Fallon on Monday, April 8, the actor, 51, reacted to diehard fans casting the Batman star to take on a potential spinoff that tells the story of Parson's iconic character Sheldon Cooper as an older man. “It is interesting. There’s definitely a resemblance,” he marveled when host Jimmy Fallon held up a side by side photo of him, Keaton and Young Sheldon prequel star, Iain Armitage. “The one thing I will say is Michael Keaton — that really looks like Michael Keaton still, doesn’t it?” Michael Keaton.

I would be amazed.” He continued, “I’ve admired that man my entire life, starting with Mr. Mom. I mean, what a great guy. He’s a wonderful actor.” Parsons went on to reveal that he once met Keaton "in passing" at an industry event though they only exchanged a “quick hello and goodbye!” Jim Parsons Says Reprising His Big Bang Theory Role for Young Sheldon Finale Was 'the Nicest Little Coda' (L) Mayim Bialik and Jim Parsons in 'The Big Bang Theory'.
