Wizards

Ralph Bakshi's post-apocalyptic sci-fi animation film Wizards, as described on its Wikipeda page, is an animated post-apocalyptic science fiction/fantasy film about the battle between two wizards, one representing the forces of magic and one representing the forces of technology. It was written, produced and directed by Ralph Bakshi. This is 20th Century Fox's first animated film and was probably one of the first post-apocalyptic feature length animation films ever released.
Due to budgetary constraints, Bakshi was unable to complete the battle sequences with the budget Fox had given him. When he asked them for a budget increase, they refused (during the same meeting, director George Lucas had asked for a budget increase for Star Wars and was also refused). As a result, Bakshi finished his film by paying out of his own pocket and using rotoscoping for the unfinished battle sequences. According to Bakshi, "I thought that if we dropped all the detail, it would look very artistic, and very beautiful, and I felt, why bother animating all of this? I'm looking for a way to get realism into my film and get real emotion." In his audio commentary for the film's DVD release, Bakshi states that "There's no question that it was an easier way to get these gigantic scenes that I wanted. It also was the way that showed me how to do Lord of the Rings, so it worked two ways."In addition to stock footage, the film used battle sequences from films such as Zulu, El Cid, Battle of the Bulge and Alexander Nevsky for rotoscoping. Live-action sequences from Patton were also featured.
Although it has a somewhat dated animation style (which we like), Wizards is an interesting post-apocalyptic animation worth checking out.
