The lead central character of Prospero from William Shakespeare's play "The Tempest" was renamed Phillip Dimitrius for this film and was played by John Cassavetes.
Son-of-a-bitch! What I wouldn't give for a different nightmare.
When a helicopter lands in Manhattan, in the last scene of the film, Philip steps out with a haircut in continuity with the early part of the story, set "18 months ago". Since the time on the island takes place 18 months later, over a 24 hour cycle, his hair should be short and gray when he lands, instead of longer and darker.
