Anthony Mackie says it wasn’t Robert Downey Jr. in Doom costume on set of Avengers: Doomsday

Anthony Mackie joked that Robert Downey Jr. was not inside Doctor Doom’s costume while filming *Avengers: Doomsday*, saying, “Robert don’t fight!” His comments add to speculation about whether Downey or another performer appears in the suit, although Mackie did not confirm who wore it.

Mackie described the set as a chance for cast members to catch up and said he spent time with Paul Bettany. That prompted speculation that Vision may appear in the film, but the two productions shared a filming area, offering another explanation. *Avengers: Doomsday* is due in UK cinemas on 16 December and US cinemas on 18 December.
