'Thor 3' 2017 Casting and Plot Rumors: There is a mystery woman in the new Avengers: Age of Ultron trailer that is giving rise to rumors that we might be seeing Natalie Portman in more Marvel universe movies.

"Thor 3" is moving forward, but no release date has been set.

A recent trailer for Avengers: Age of Ultron, shows an early scene where we see Ultron come into a room in pieces of a broken Iron Man suit. Ultron talks with the team of Avengers, including Bruce Banner, Thor, Iron Man, Captain America, Black Widow, War Machine and Maria Hill. But there is a mystery woman standing next to Thor. Does that mean we will get to see Portman is in the next movie?

Natalie Portman has been in two Marvel movies without saying much about it. The V for Vendetta actress makes a brief appearance in the next Marvel film. Her appearance in the new Avengers film might be her last.

In an interview with SciFiNow before "Thor: The Dark World" opened, Natalie Portman said "There are definitely many strong women, but it will be exciting when there is a central female character which I think is coming - I have heard is coming. And, of course, also a central non-white character will also be exciting. Title characters."

Natalie Portman says there have been strong female supporting characters in Marvel movies, "They do definitely have strong female characters in them, and I think it's a testament to the people who run Marvel - their respect, their just normal human respect for women, the way they want to characterize them."
