A worker at Walt Disney World is “recovering” after being injured by a 400-lb (180kg) runaway fake boulder prop in an incident that was caught on video, the Florida theme park confirmed.
The incident took place at the Indiana Jones Epic Stunt Spectacular! during a live recreation of a famous scene from the film.
Video shows the boulder rolling towards the audience as a staff member jumps into its path, preventing it from reaching the crowd.
I think that is best referred to as an “ultralight performance boulder” rather than a “fake boulder”.
