Alan Cumming has revealed that working on Marvel’s upcoming film Avengers: Doomsday was one of the most unusual acting experiences of his career. In an interview with Gold Derby published on August 19, 2025, the Emmy-winning actor explained that the secrecy surrounding the production left him largely in the dark about what was happening during filming.
“I did the entire film in isolation,” Cumming said, noting that the project relied heavily on green screens and digital effects. According to him, the studio even assigned actors “fake names” during shooting, making it nearly impossible to know which co-stars were involved in particular scenes. “I don’t know who I was acting with half the time,” he admitted.
Cumming also recalled that he once “broke the internet” after dropping a remark about the movie, only to later acknowledge he might have gotten the details wrong due to the limited context he was given on set. Marvel, known for maintaining extreme levels of confidentiality on its projects, appears to have taken its secrecy measures to new heights with Avengers: Doomsday.
Although he refrained from offering specific plot information, Cumming’s comments highlight the increasingly complex and fragmented ways blockbuster films are produced, often with actors performing without full scripts or direct interaction with their fellow cast members. His experience reflects Marvel Studios’ longstanding strategy to prevent leaks and maintain surprise for audiences.
Beyond his role in Doomsday, Cumming is also busy with Peacock’s hit reality competition series The Traitors and confirmed his return as Sandy Frink in the planned sequel to Romy and Michele’s High School Reunion. But when it comes to Marvel, he admits his knowledge remains as limited as the fans eagerly awaiting the next chapter of the franchise.
