Before he starred in flicks such as "Law Abiding Citizen" and "The Bounty Hunter," Gerard Butler was studying law at the University of Glasgow and also spent two years as an intern at a law firm.

But of course, he didn't mess it up, as he made a hugely successful 180-degree career change into the entertainment business, and the rest is history!
