'Avengers: Age of Ultron' Trailer: Mystery Woman Spotted Next To Thor May Be Korean actress Claudia Kim

Marvel has released the first trailer for “Avengers: Age of Ultron”, and some super fans can’t stop talking about the mystery woman standing next to Thor in one scene.

The mysterious female doesn’t appear to be Natalie Portman’s “Thor” character Jane Foster or Jamie Alexander’s Lady Sif, but many are speculating it is Marvel newcomer Korean actress Kim Soo-hyun, also known as Claudia Kim.

Screen Rant reported back in March the Marvel production cast Kim in a mystery role.

“After a long wait, I’m happy to be back with great news. I have a lot to do ahead of me, but for now, the words ‘Welcome to the Marvel Universe’ are amazing and kind of overwhelming. I was a fan of Marvel Comics, and if you really like something, looks like fate can make it happen,” Kim wrote on her Twitter back in March.
