This was Director Ralph R. Clemente's final picture. He died during the editing process.
Director Ralph R. Clemente went to England to visit his former student, fellow Director David Nutter, who was directing an episode of Game of Thrones that he would eventually win an Emmy for. Nutter asked Clemente to be an extra for a scene, and he did. Unfortunately, Clemente's cameo ended up on the cutting room floor. When Nutter accepted his Emmy for the episode, he thanked Ralph Clemente by name for teaching him everything he knows.
