The villainous Red Skull -- whose fate has been unclear since he disappeared in a Tesseract-induced glow at the end of 2011’s Captain America: The First Avenger -- makes a surprise return appearance in Avengers: Infinity War. But that’s not original actor Hugo Weaving playing the character this time around. The Walking Dead’s Ross Marquand succeeds Weaving in the role of the Hydra leader-turned-Soul Stone keeper on the planet Vormir.
