Bad actors have ruined plenty of films. This is especially true in the superhero genre, where taking on the role of a classic Marvel or DC villain can really challenge some actors. Classic examples include Topher Grace as Venom, Peter Sarsgaard as Hector Hammond, and Arnold Schwarzenegger, king of the one-liner, as Mr. Freeze.
Sometimes bad CGI is to blame for bad villains. But terrible acting plays a part too. Regardless of how good they are in other films, all the actors on this list are guilty of some really bad comic book movie acting. For some, it's how they fail to add depth to a character. Others were cast poorly and simply didn't have the right body types to bring bulky villains to life. Still others were the victims of poor directing, bad wardrobe choices, or horrible writing, and their performances suffered as a result.
