LOS ANGELES — A worker at Walt Disney World was injured after a fake boulder rolled off its track during a live show at the Florida theme park, a Disney spokesperson said.

The incident took place at the Indiana Jones Epic Stunt Spectacular! during a live recreation of a famous scene from the film.

A video footage showed the 400-lb (180kg) runaway boulder rolling toward the audience and the staff member jumping into its path, preventing it from reaching the crowd.

The staff member did not appear to stand up immediately, and other workers are seen running to his side.

"We're focused on supporting our cast member, who is recovering," Disney said in a statement on Wednesday. "Safety is at the heart of what we do, and that element of the show will be modified as our safety team completes a review of what happened."

The scene from 1981's Raiders of the Lost Ark shows Indiana Jones — played by Harrison Ford — outrunning a giant boulder triggered by a booby trap, before leaping to safety.

A spokesperson for Disney did not confirm that the boulder was the cause of the incident, but told CBS News that "a prop moved off its track".

One witness told People magazine that the worker had "saved" the audience from being injured. "It was a crazy experience and definitely one that we will remember."

In one video of the incident, a man behind the camera is heard saying: "He literally saved our lives, that guy." — Agencies
