2) The Leader
Clearly the makers of The Incredible Hulk took lessons from the X-Men movies in cramming in characters from the comics. As well as Doc Samson and Cho, supervillain The Leader also makes an appearance.
In the movie, Sterns is a scientist who works with Emil Blonsky to tap into the power of The Hulk. The last time he is seen, an accident causes some of Bruce’s blood to mix with an open wound on his forehead. As his head swells, Sterns starts to smile…
This is naturally a nod to the enlarged cranium of the character in the comics, who believes his intelligence casts him above others, hence the name The Leader. Clearly, Sterns was being set up for an appearance in a villainous role in a future Hulk movie. However, as we all know, a sequel never materialized.
