Rami Malek fell off the stage shortly after the Oscars ceremony concluded and an ambulance had to be called. He did his best to hold his statue upright throughout the whole incident. Here's more from People Magazine:
Paramedics were then called to treat the actor, who was moved into a chair in the front row and then onto a more private area backstage. Despite the fall, the actor did not show any outward signs of being injured as he spoke in the press room after the incident.
