Doctor Doom should soon debut in the Marvel Cinematic Universe, and the perfect actor to play the iconic Marvel villain could already have been a part of the MCU. Doctor Doom is one of the best villains in all of Marvel Comics; however, that has not exactly translated into live-action. The villain appeared in three Fantastic Four movies, which did not exactly do right by him or Marvel's First Family. Julian McMahon's Victor von Doom in the 2000s Fantastic Four movies showed promise but never met it, and Toby Kebbel's Doom sank in the ill-received 2015 Fantastic Four reboot.
