Leonardo DiCaprio played an eccentric character in 'The Aviator,' but in his own life growing up DiCaprio suffered from OCD.
'I had the thing where I would walk to school and have to walk, you know, go back a block because I didn't step on a crack," DiCaprio told Katie Couric in 2004. 'And I felt like something was going to go wrong if I didn't do that.'
The actor says he's in control of his obsessive urges now.
