Our hearts and thoughts are with his family, friends and colleagues at this time, and our full support is behind the investigation into the circumstances of this terrible event," said the studio in a statement.
The person, who was not a stunt performer, was reportedly preparing an underwater action scene when the accident occurred. Disney is investigating the circumstances.
Directed by Gore Verbinski, the film follows Native American spirit warrior Tonto (Depp), who recounts the untold tales that transformed John Reid (Armie Hammer), a man of the law, into legendary The Lone Ranger. It hits theaters July, 2013.
