No opening credits for actors, writers, producer, director, etc. are shown, with the story beginning right after the title. Although by the 1990s it had become quite common for major films to not have opening credits, it was still unusual in 1968.
The original theatrical release had Ligeti's Atmospheres to a black screen for roughly 8 to 10 minutes before the movie began, and Strauss' The Blue Danube well after the end credits to a black screen.
The traditional "roaring lion" logo for MGM was not used in this film. Instead, the newly designed corporate logo for Metro-Goldwyn-Mayer was used, along with the letters "MGM", all in white against a blue background.
"Thus Spake Zarathustra" is the only musical piece in the film whose conductor and orchestra are not mentioned in the closing credits. For all other pieces, the orchestra which plays it, and the conductor who leads it, are given screen credit.
