All fans of The Big Bang Theory know Johnny Galecki as Dr. Leonard Hofstadter, but it is doubtful you remember him in Christmas Vacation, his first big break as Chevy Chase’s son, Rusty Griswold.
Galecki, was only 14 years old when the holiday classic came out, and now, twenty-five years later, he is a star on his own sitcom, netting a hefty $1 million dollar salary per episode. I’ll bet 39 year-old Galecki has come even further than his 14 year-old self ever dreamed.
