- In 1997, a fierce sandstorm destroyed several of the Tatooine sets in the desert outside Tozeur, Tunisia. Filming resumed two days later. George Lucas considered this a good omen, as the very same thing had happened during filming of the original Star Wars (1977).
- During filming Ewan McGregor made lightsaber noises as he dueled. It was noted and corrected during post production.

- In the original trilogy, lightsaber activations and deactivations happened off-screen most of the time to prevent the "jumps" that would occur when the film was stopped to allow the "activated" lightsaber props to be substituted for the deactivated handles.

- Many details of the pod race resemble the Norwegian animation classic Flåklypa Grand Prix (1975), including the sabotage, the late start, the engine trouble, the dirty tricks and even elements of the camerawork. And they both resemble the opening race from Grand Prix (1966).
- The video and sound effect of Queen Amidala's message when she contacts the federation ship at the beginning of the movie via video transmission is a reference to the Flash Gordon serials of the 1930s (Flash Gordon (1936/I), Flash Gordon's Trip to Mars (1938) and Flash Gordon Conquers the Universe (1940)), where video transmissions always start with the same video and sound effect.

- It appears that the other head of the podrace announcer is simply saying the same thing as the first head, but in Huttesse instead of English. This isn't so. Originally what the second head said was supposed to be subtitled, and the screenplay of the movie contains a translation of all of his dialogue.

Williams, John' had the lines "Under the tongue root a fight most dread, and another raging, behind, in the head" translated into Sanskrit. The translation sung in the movie is as follows: "Korah Matah Korah Rahtahmah Korah Rahtamah Yoodhah Korah Korah Syahdho Rahtahmah Daanyah Korah Keelah Daanyah Nyohah Keelah Korah Rahtahmah Syadho Keelah Korah Rahtahmah Korah Daanyah Korah Rahtahmah Korah Daanyah Korah Rahtahmah Nyohah Keelah Korah Rahtahmah Syadho Keelah Korah Rahtahmah Korah Korah Matah Korah Rahtahmah Korah Daanyah Korah Rahtahmah Nyohah Keelah Korah Rahtahmah Syadho Keelah Korah Rahtahmah Korah"
- The planet Coruscant was originally the brainchild of Timothy Zahn, first appearing in his novel "Heir to the Empire".
