The child with the red dress is from Schindlers List. And I would say Dracula (1931) is also in the picture with Bela Lugosi. Audrey Hepburn in the left upper corner must be taken from Breakfast at Tiffany's.
The Audrey Hepburn pic could also be from Roman Holiday where she plays that princess falling in love with Gregory Peck ... hach ...
btw, we see HIM again in the middle in the movie To Kill A Mockingbird
And I know the woman in the left down corner from a wtm snapshot, La Strada, I think. [oh, muten already got that]
@ Mimimi: Just an idea which suddenly sprang up in my mind: Couldn't you in the end, when all movies have been solved, post the picture again where one sees which movie belongs to which scene?
The Schindler's List --> The little girl in a red coat (at the bottom, second from the right) To Kill a Mockingbird --> Gregory Peck with his daughter (at the bottom, third from the right) Casablanca --> Humphrey Bogart and Ingrid Bergman (the big picture) Rashômon --> The guy in the right corner (or maybe Shichinin no samurai)
