A crew member on Johnny Depp's latest film The Lone Ranger has drowned on set while preparing an underwater sequence.
The diver was pulled out of a tank on the set after another crew member noticed that no bubbles were surfacing from his scuba equipment.
"We regretfully confirm that a Lone Ranger crew member has passed away after being taken to a local hospital," a Walt Disney spokesperson said.
"Our full support is behind the investigation into the circumstances of this terrible event."
TMZ reports the man was helicoptered to a nearby hospital but paramedics were unable to restart his heart.
He was declared dead on arrival at the Los Angeles hospital.
It is understood that the movie was not filming at the time.
It is not the first safety incident the $200 million western has endured, the Los Angeles Times reports.
In May a stuntman was injured on set, while Depp himself said he narrowly avoided injury after being thrown from a horse.
