He grew up in Oak Park, Illinois, and had an early talent for making up stories. This creative streak led to his career as an actor. He made his debut in 1987 on the CBS miniseries, Murder Ordained. Johnny famously played Rusty Griswold in National Lampoon’s Christmas Vacation in 1989 and the role of David Healy on the U.S. sitcom, Roseanne, from 1992 to 1997.

Though Johnny appeared on a handful of television series, he wouldn’t make his triumphant return until 2007, when he was cast as Dr. Leonard Hofstadter in the CBS hit sitcom, The Big Bang Theory.
