Tom Holland revealed on the “Rich Roll” podcast that he was one of the select few people who knew about Robert Downey Jr.’s bombshell Comic-Con reveal, in which it was announced that the former Iron Man/Tony Stark actor would be returning to the Marvel Cinematic Universe as the villainous Doctor Doom.

Holland and Downey had killer chemistry throughout their appearances together in the MCU, including Civil War, Spider-Man: Homecoming, and Avengers: Infinity War. And it sounds like that began in the audition room before it extended to an actual film set, with Holland sharing that the Oscar-winning actor helped give him freedom to improvise.
