In an interview, Chris Evans (Captain America) and Chris Hemsworth (Thor) along with the rest of the Avengers (Infinity War?) cast played a game where they had to guess who it was by a picture of their arm. A picture of Robert Downey Junior’s arm was first and it was super muscular. Everyone was so surprised and when the interviewer told the Chrises, Chris H. went “Since uh-when”.
