One of those men, Richard Stephens, 89, went to visit for the set of the Cage film in Alabama recently, which is called USS Indianapolis: Men of Courage.
'I think it's going to be a good movie,' Stephens told The Indy Star.
'I told (Cage) I didn't like movies that were fictional, and they should be trying to show more respect, they should be using the facts.
'He said it's going to be pretty true to facts.'
Stephens was only 18 when the ship sank.
