Stand by Me
55. The cigarettes the boys smoked in Stand by Me were made out of cabbage leaves.
56. Stand by Me is closely associated with director Rob Reiner, but he actually wasn't the original director attached to the film.

63. In the original script for Gremlins, Gizmo was supposed to be the villain, turning into the gremlin Stripe and becoming the leader of the gremlin pack. Steven Spielberg (who produced the film) suggested they change that plot point because he felt Gizmo was cute and audiences would want to see him throughout the film.
64. Gremlins and Indiana Jones and the Temple of Doom (which also both happen to be Spielberg-produced films) were responsible for the creation of the PG-13 rating system. Both films, while rated PG, contained lots of violence, but not enough to warrant an R rating.
65. Tim Burton almost directed Gremlins, but was eventually passed over because he had never directed a feature length film.
66. Michael Uslan, the producer of Batman, envisioned Jack Nicholson playing the Joker in 1980, after seeing a photo of him as Jack Torrance from The Shining in the New York Post. Ulsan took Wite-Out and markers, and sketched out the Joker over Nicholson's face.
67. Fans protested when it was announced that Michael Keaton had landed the role of Bruce Wayne/Batman. Warner Bros., the studio behind the film, received 50,000 angry letters.
