John Galecki as Leonard Hofstadter
42 year old John Galecki is known for two iconic roles, obviously as the nerdy physicist Leonard Hofstadter from The Big Bang Theory (TBBT), but what about the other? That’s right, we’re talking about his Roseanne days when he was the awkward boyfriend David Healy.
The cellist is set to reprise his role as Healy for an eight-episode mini series coming out in 2018. And if you can’t wait for the mini-series, there’s always The Big Bang Theory of course! And as it’s in season 11, you’ve got plenty to watch.
