2.  Decided to take a break from acting after making the 2001 movie Manic to attend New York's Columbia University, where he studied history, literature, and French poetry. Although he dropped out in 2004 to return full-time to acting, he called the university experience "one of the smartest things I've ever done."

3. Got the part of Arthur in Inception after James Franco turned down the role.
