One of the many new additions to the cast of Marvel Studios' upcoming Avengers: Age of Ultron is German actor Thomas Kretschmann as the villain Baron von Strucker, a high-ranking member of Hydra. Strucker's involvement in the upcoming film is still unknown, but rest assured it won't be Kretschmann's only appearance as the Baron. In an interview with B.Z. Berlin (via CBM), Kretschmann confirmed that he has signed on for multiple appearances as the character, saying:

"I have a multi-picture deal which means I will not only appear in the 2nd part, but they're planning with me for a longer period of time. But I don't know details yet, they're keeping their cards close to their chest – top secret!"

When asked if he was nervous about performing in such a big film, Kretschmann replied:

"Oh yes, I was nervous. I was over prepared; then on the set I went up to Joss Whedon, who passes for a genius, and said 'this is my first day, this is huge, please have patience with me, I'm a bit nervous.'"

Given that principal photography on the film won't start until later this month, it's interesting that Kretschmann would mention speaking with director Joss Whedon on the set. Is it possible that he'll be appearing in something before Avengers: Age of Ultron? Sound off with your theories below!

Also starring Robert Downey Jr., Chris Hemsworth, Mark Ruffalo, Chris Evans, Scarlett Johansson, Jeremy Renner, Samuel L. Jackson, Aaron Taylor-Johnson, Elizabeth Olsen,and James Spader, Avengers: Age of Ultron will hit theaters May 1, 2015.
