The Avengers will have more than just Ultron to contend with when the team assembles in Age of Ultron.

As filming draws nearer for the Marvel Phase Two capstone film, writer/director Joss Whedon has already announced several new characters but late casting is still yielding a few secrets.

The film is currently looking for Caucasian man between the ages of 40 and 50 to take on the role of Baron Von Strucker, according to the Latino Review.

Von Strucker, a practically invincible member of the WWII era group HYDRA, will be a supporting character at the beginning of the film, according to HitFix. The villains purpose will be to bringing Quicksilver (Aaron Tyler-Johnson) and the Scarlett Witch (Elizabeth Olsen) in the picture.

The two Eastern European siblings will either be working for or against the ex-Nazi, and this connection will put them in league with Earth's Mightiest Heroes. However, the intro could have something to do with the reason that the two mutants will have a bit of trouble with their new colleagues.

"You know, they had a rough beginning," Whedon told IGN. "They're interesting to me because they sort of represent the part of the world that wouldn't necessarily agree with The Avengers. So they're not there to make things easier. I'm not putting any characters in the movie that will make things easier."

The Avengers: Age of Ultron will hit theaters on May 1, 2015.
