German actor Thomas Kretschmann has signed a deal to play villainous former Nazi Baron Wolfgang von Strucker in several movies, including Avengers: Age of Ultron and possibly a cameo in Captain America: The Winter Soldier, according to websites ComicBookMovie.com and Dark Horizons.
Kretschmann, who has already played Nazi officers in films such as The Pianist and Valkyrie, will play the battle-scarred leader of HYDRA, whose agents were seen battling Captain America in the World War II period of Captain America: The First Avenger. In the comics, von Strucker is a nemesis of Cap, the Avengers and S.H.I.E.L.D., which makes him a particularly appropriate addition to the Marvel movie universe. Also, he can give Loki a break from multifilm villainy. After all, the Norse god of mischief cannot be in every Marvel film!
