10 Actors Who Thought They Were Playing Other Comic Book Villains

10. Peter Sarsgaard (Green Lantern)

Warner Bros.

Who He Was Supposed To Play: The big-headed Hector Hammond is meant to be a silent, power-hungry telepath. Spurned by Carol Ferris and promptly given amazing abilities, Hammond decides that he wants the Green Lantern's power. He can barely move but the hatred that drives him still makes him absolutely terrifying.

Who He Really Played: Ironically, Peter Sarsgaard's spurned outcast take on the character didn't resemble Hammond but someone already in the film. Though she had yet to transform into a villainess, it was Carol Ferris’s evil alter-ego Star Sapphire that he better embodied. Despite her being female and considerably less deformed, his performance shared very similar motivations and influences to her character.

Sarsgaard's Hammond is presented as a weird guy who is simply made evil by the fear energy, much like Carol Ferris was corrupted by the Star Sapphire. Despite his connection to Carol, he becomes much more obsessed with Hal Jordan, and like Star Sapphire, uses his new powers to strike at him. Beyond that, there’s not much driving either character, they’re simply made crazy by cosmic energy. In essence, thanks to Sarsgaard’s creepy performance, Hammond went from a silent, manipulative genius in the comics to something more closing resembling Hal Jordan's vengeful ex-lover in the film.
