Long overdue, Marvel fans need no reminder that Tim Blake Nelson's iconic turn as Samuel Sterns—the scientist who would become the powerful leader—was first seen way back in 2008's The Incredible Hulk.

Long overdue, Marvel fans need no reminder that Tim Blake Nelson's iconic turn as Samuel Sterns—the scientist who would become the powerful leader—was first seen way back in 2008's The Incredible Hulk.
Nelson has hinted at a much more faithful adaptation of the Leader's comic book roots, saying that fans could turn to the source material to get some idea of where the character is headed. He is quite convinced that all of that is going to be literally breathtaking when he views the villain in his cinematic avatar.
The fact that he changes from a despairing to an ecstatic state only as an actor is an example of the timeless appeal of this character. Nelson's surprise return has him overjoyed, as he has come to terms with the fact that he will never again play the leader. He has publicly thanked Kevin Feige, the head of Marvel Studios, for turning this vision into a reality.
