With Chris Evans returning to Avengers: Doomsday, and everyone speculating who he will be playing, there seems to be one possibility that we’ve all been ignoring. Chris Evans is one of the most significant actors in MCU history, starring as Captain America for nearly a decade, standing alongside Robert Downey Jr.’s Iron Man as the two most important characters in the cinematic universe. The MCU timeline would look significantly different without Evan’s Steve Rogers and Downey Jr.’s Iron Man, and it was thus perhaps only a matter of time until they both returned in some capacity.
