10 Awesome Things Actors Have Done While In Costume

9. Jaimie Alexander Visiting A Children's Hospital Dressed As Lady Sif

One of the fiercest warriors in Asgard, Lady Sif, took time from her duties protecting the Nine Realms to visit some of Midgard's toughest fighters - the patients at Children's Hospital Los Angeles. As if we needed another reason to be in love with her, Jaimie Alexander, who of course portrayed the character in Marvel's "Thor: The Dark World", spent an afternoon last year visiting dozens of kids, handing out signed DVDs and posters as well as giving them the chance to pose with Sif's own shield and sword. It€™s pretty awesome to see our fictional superheroes turning into real life superheroes to help out kids struggling with disease. Who says you can't be a complete bad-ass as well as a genuinely good person? This is exactly the reason why we want to see Alexander portray more comic book heroines, like Wonder Woman. And Baroness. And Teela. Can't she just be in every movie, ever?
