I will always have a soft spot for John Cusack thanks to his memorable '80s roles as the sharp but self-deprecating underdog. (You know you love Lloyd Dobler!) As years pass he continues to pop up in movies —whether he's playing the sweet hero in a rom-com (Serendipity), or a record-store owner in the midst of a breakup (High Fidelity). This Friday he'll be a dad facing the end of the world in 2012. Sure, you're probably familiar with his films, but just how sharp are you? Test your I.Q. by taking my quiz!
