According to Variety, he may have broken his ankle in two places and hurt his hip. He is scheduled to see a doctor this week.
Video of the stunt showed Cruise in a harness while jumpiing in between two buildings. He appeared to fall short of the second building and slammed into it. He could be seen limping toward crew members and collapsing, before walking back toward the first, taller building and being pulled back by the safety team.
Cruise is well known for doing most of his own stunts. In 2015, he clung to the wing of a moving plane while filming “Mission: Impossible Rogue Nation.”
