James Dean's article written for LIFE Magazine was not very popular at the time when it was first released.
Dane DeHaan turned down the role of James Dean five times as he felt intimidated playing such a respected figure. His wife, Anna Wood, eventually convinced him to take on the role.
Pier Angeli (Alessandra Mastronardi) asked Dennis Stock (Robert Pattinson) to compare between James Dean and Paul Newman as they were both newcomers. The fact is, that Newman's career went high after collecting all of the roles destined to be Dean's after his death, specifically Somebody Up There Likes Me (1956) (with Pier Angeli) and The Left Handed Gun (1958).
Both actors who have portrayed Harry Osborn in live-action Spider-Man movies (Dane DeHaan and James Franco) have also portrayed James Dean.
