Trivia: Miley Cyrus has a brief cameo at the end of the film in the musical number "All For One". She is seen in a quick close-up, wearing a yellow top, dancing with other people on the rocks around the pool.
Trivia: At the very beginning, David sits in front of his newest drawing, showing a man with two guns, a rose right of him and a tower far behind on the left side. This drawing shows Roland, a character out of "The Dark Tower", a well-known series of books from Stephen King. This drawing is shown again, some time later after the storm, and David tells that this drawing was meant to become a film poster. (00:00:30)
