Korean actress Kim Soo Hyun has confirmed on Twitter a rumor that began back in January - that she has joined the cast of "Marvel's Avengers: Age of Ultron". She tweeted:
"After a long wait, I'm so 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 it looks like fate can make it happen."
It's still unknown what role she will play in the film, an unnamed Marvel official telling Korean news agency OSEN:
"It would be a spoiler, so we can't tell you which character Kim Soo Hyung will play. Marvel always prohibits telling too much about the story. Her character is already decided and the scene is already written so we cast Kim Soo Hyun, but we can't let you know about her character. We only can say that her character is a substantial supporting role."
Filming is slated to begin in Incheon City, South Korea shortly.
