When you think of The Big Bang Theory, Johnny Galecki’s face probably swims in front of your eyes – because he is arguably one of the most famous faces from the show. Yet, his role on the show was not the casting decision that changed the course of his career. In fact, he had been acting for decades before he scored himself the role of Leonard Hofstadter! Galecki made his first Hollywood debut in 1987 when he appeared in the drama mini-series, Murder Ordained. After that, he starred in the hilarious comedy, National Lampoon’s Christmas Vacation and more.
