Baron Wolfgang von Strucker is going to be sticking around in the Marvel Cinematic Universe, actor Thomas Kretschmann revealed in an interview with B.Z. Berlin. As spotted by The Hollywood Reporter, the actor confirmed his role was signed in “a multi-picture deal.”
Now, don’t expect H.Y.D.R.A. Island or the Thunderbolts to jump right to the forefront of the MCU right after Avengers: Age of Ultron, Kretschmann’s first film with Marvel Studios, however. The multi-picture deal has become something of a standard issue for the studio, and for most others who are telling superhero stories. They fully recognize that these are serialized stories with ongoing issues, and want actors (and thus, their characters) locked down for future use.
Even Kretschmann admitted as much, saying “I don’t know details yet, they’re keeping their cards close to their chest - top secret!” The implication is that there was no specific additional appearance, just that they wanted to keep that door open. Still, with the character’s affiliations - both as allies and enemies - across the Marvel Universe, keeping him around for more does open up many more character introductions and possibilities for the future of the MCU.
