Anthony Mackie (“Altered Carbon”) and Daveed Diggs (“Snowpiercer”) tackle a conversation on the Marvel Cinematic Universe, race, and politics for “Variety Studios Actors on Actors.” Mackie, who plays Marvel character Falcon, says it bothers him that he was one of the few black people among the crew for the past seven films he’s worked on with the franchise. Diggs admits he had a hard time moving past some of the violent scenes of “Snowpiercer.”
