Leonardo Dicaprio was snapped hanging out of a window ledge while filming his upcoming flick, Inception, in downtown Los Angeles, California on Thursday.

In another shot, his co-star in the film, Marion Cotillard, is also shown peeking her head out a window talking to the Titanic star — very Romeo And Juliet!
