Julius Onah discusses the look of the MCU villain: "You want to make sure that even with these heightened characters, it fits into the world of the film."

Brave New World brings back one of the Marvel Cinematic Universe’s most underutilized villains after a 16-year absence. Samuel Sterns (Tim Blake Nelson) was last seen in 2008’s The Incredible Hulk when exposure to Bruce Banner’s blood triggered his transformation.

Brave New World director Julius Onah reveals how the movie's post-credits scene came to be and what it might mean for the Avengers.
