In my recent review of the 1968 film 2001: A SPACE ODYSSEY, I wondered about the alleged Nietzschean inspirations of the Kubrick-Clarke script, particularly with respect to the ending, wherein astronaut Bowman is transformed into a sort of superman-- or maybe "super-fetus." Because Kubrick's film utilized so little exposition, though, it's tough to figure out what's going on with Bowman when he transforms. Does he incarnate the Nietzschean idea of "self-overcoming?" I wasn't able to find an online copy of the final 2001 script, which I believe Kubrick changed a lot during the movie's production. The novelization by Kubrick's co-writer Arthur C. Clarke does include a lot of mental exposition by Bowman when he transforms. However, Clarke's description of the process is pretty vague. Novel-Bowman doesn't behold a monolith in his fantasy-bedroom. He goes to sleep and feels like "something invaded his mind," though one can only assume that his alien controllers have triggered this process. He experiences a vision of time flowing backward, and as he re-experiences old memories, he regresses to the super-fetus. Then, as Bowman-Fetus transitions into outer space, he then sees the Jupiter monolith. But Clarke never directly says that the aliens have transformed Bowman, though he may have assumed that all readers would make that assumption.
I then gave a quick look to Jack Kirby's 1976 adaptation of 2001. Obviously Kirby had seen the film by then, as he duplicates the scenario of the bedroom-monolith, among many other scenes. Maverick that he was, Kirby diverges from the film in many ways too, sometimes just out of personal preference. According to one online source, Kirby also borrows elements from the Clarke novelization as well, one example being that Kirby has the primeval ape-men hunt Clarke's warthogs, rather than Kubrick's tapirs. But though I doubt Kirby ever read much if any Nietzsche-- it's in the conclusion of the 2001 adaptation that I found the most Nietschean statement about Bowman's transformation. To be sure, the first part of the "explanation" is jumbled, as a Kirby Kaption says, "What is the end or beginning to something that has known neither-- mortally is a condition of man." I can only assume Kirby meant to write "mortality," because the following sentence is, "And he must be taught to surmount it..." That's all the internal monologuing Kirby gives us before the monolith begins its transforming process, but the whole ideal of "surmounting death" bears comparison to Nietzsche's idea of "self-overcoming." Then, in the last few pages, Kirby totally dispenses with the endings of both Kubrick and Clarke, claiming that the Star Child is "the first of many new ones," implying that the monolith is programmed to transform other humans into a race of super-psychics. It's kind of a wacky take on both movie and novelization, but I must admit-- it's Kwintessential Kirby!
