Tom Hiddleston in The Avengers
- The role: Loki, the villain facing off against all of the Avengers.
- Where you've seen him before: In last Summer's Thor originating his role as Loki, and as F. Scott Fitzgerald in Midnight in Paris.
- Why we like him: The Avengers may be chock-full of hot superheroes, but Hiddleston steals tons of scenes as Thor's bad-boy brother.
