The Big Bang Theory Cast: Where Are They Now?
2. Johnny Galecki - Leonard Hofstadter
Alongside Penny, Leonard Hofstadter became part of the show's power couple, once they finally got together, that is. Depending on the situation in question, Leonard is the most capable of adapting to social situations over Sheldon, Raj, and Howard, although he still has his nerdier moments. He wouldn't be Leonard without those traits, after all.
Not long before the culmination of his role on TBBT, Johnny Galecki reprised his role of David Healy in Roseanne, which returned for an eight-part mini series in 2018. That role would also see Galecki star in the Roseanne spinoff The Conners, with four episodes as David under his belt at the time of writing. Galecki's only other role came as Henry in A Dog's Journey, which was released approximately two weeks before The Big Bang Theory finale aired.
As well as being an exceptional onscreen performer, Johnny's work also translates behind the scenes, as he's produced on a number of shows. Most recently, he was credited as having a helping hand on eight episodes of SciJinks and 13 episodes of Living Biblically.
Galecki and partner Alaina Meyer welcomed their son Avery to the world in December 2019, so perhaps that's why we haven't seen too much of Galecki on our screens as of late.
