I was just browsing imdb and always wondered why in some movies an actor/actress will appear in the credits as the character but right beside in parenthesis "As Name"? Check out Dane DeHaan's profile as an example:
There are two in his profile, one for Lincoln - Second White Soldier (as Dane Dehaan) and one for At Risk - Cal Tradd (as Dane Dehaan)
Can anybody provide a reason for this? Or is this an imdb only tweak?
