The period drama focuses on Life magazine photographer Dennis Stock and a friendship he struck up with actor James Dean, played by Deehan. Stock and Dean took a trip together from Los Angeles to New York as part of an assignment for Life to photograph the actor.
Pattinson was spotted earlier in the week riding on the back of a motorcycle driven by DeHaan for the film.
