The Ultimate Trip Becomes the Ultimate Illustrated Adventure! One-Shot; Movie-Adaptation Marvel published the adaptation in its then-common treasury edition format featuring tabloid-sized pages of roughly twice the size of a normal comic book.[1][2] The story is a close adaptation of the events of the film, but differs in the fact that Kirby incorporated additional dialog from two other sources: the Clarke/Kubrick novel,[3] and a copy of an earlier draft script of the film that included the more colloquial-sounding version of HAL 9000, as originally voiced by actor Martin Balsam before Douglas Rain took over. In addition, the comic narrative captions describe the characters' thoughts and feelings, a significantly different approach from that taken by the film. The treasury edition also contained a 10-page article entitled "2001: A Space Legacy" written by David Anthony Kraft.
