Dane Dehaan and Robert Pattinson are teaming up onscreen to tell the story of James Dean's friendship with photographer Dennis Stock. DeHaan will portray the tragic movie star, while British actor Pattinson will play the Life magazine lensman in Anton Corbijn's new film. Stock was a young photographer when he was hired to take shots of a pre-fame Dean. The two men quickly became friends and embarked on a cross-country trip, during which the snapper captured a collection of iconic images of the actor. DeHaan isn't the first actor to play Dean onscreen - James Franco famously portrayed the East of Eden star in a 2001 TV movie.
