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."
According to The Hollywood Reporter, the unnamed crew member was not a stunt performer and is said to have died while prepping for an underwater action scene, and did not die during filming. Disney is said to be investigating the circumstances.

Directed by Gore Verbinski and produced by Jerry Bruckheimer, the film is scheduled ride into theaters on May 31, 2013.
