Superhero Stars Step Out For Captain America Premiere

Superhero celebs put away their capes and shields to don suits and ties for the Captain America premiere at, appropriately, the El Capitan Theater in Los Angeles Tuesday.

Chris Evans (Captain America), Chris Hemsworth (Thor) and Robert Downey Jr. (Iron Man) all came out in support of the film. The question is ... which hero looked sexiest?

Our vote is for Hemsworth ... what's with the Elton John glasses, Chris Evans?! This was your big night!

The trio will star, along with Scarlett Johansson, Jeremy Piven, Mark Ruffalo and Samuel L. Jackson (who also hit the premiere) in the upcoming Avengers movie.

Also at the premiere was Vanessa Hudgens with her newly shorn hair -- see it in our video and gallery below!
