* WhatCouldHaveBeen:
** Jodorowsky and MarilynManson were planning to do a sequel to ''El Topo'' called ''Abelcain'' but budget issues (along with a lawsuit with Allen Klein over the rights) canceled it.
** The whole story of his ''Film/{{Dune}}'' film. In fact, without the film and its collapse, the visual effects team that made ''Alien'' (especially HRGiger, Dan O'Bannon and Jean Giraud) would likely never have assembled and science fiction on film would be a lot different.
