MCU Phase 4: Every Single Character Confirmed (So Far)

46. Alexei AKA The Red Guardian (David Harbour) - Black Widow

The legend that is David Harbour has been confirmed as part of the Black Widow cast for some time, but who he was playing was kept under wraps - with rumours, weirdly, of him playing The Thing for a while there. But we now know that he will be playing the Red Guardian, a super-soldier who is basically the Russian Captain America.

The idea of other super-soldiers is a great one to explore, considering the missed opportunity in Captain America: Civil War and we can only hope that Red Guardian's qualifications ensure that there are going to be some seriously good fight sequences. Even if it is a little strange to see Harbour playing a bad guy on the back of his loveable roguish hero in Stranger Things.
