The film’s villain, Hector Hammond (played by Peter Sarsgaard) takes centre stage here, as revealed in a tweet by Cine Heroes. In the film, Hammond is the son of a senator whose interaction with an alien substance causes him to mutate and develop telepathic and telekinetic abilities.
Sarsgaard is pictured here without his admittedly daft-looking, bulbous forehead, which is predominant in the clips from the trailers. Presumably it grows as his powers get stronger.
