Apollo 13: Jim Lovell, the astronaut portrayed by Tom Hanks, makes a cameo at the end of the film when the astronauts are retrieved from their capsule and brought safely aboard the ship. He was asked by Ron Howard to wear the uniform of a US Navy admiral for his appearance but Lovell said that he would prefer to play the role in his old captain’s uniform because that was the rank he held when he retired from the navy. Hence the “admiral” listed in the film’s credits is only wearing the four bars of a captain on his shoulder boards.
