Though it's labelled 'the fourth landspeeder' on a technical drawing, the small pod-like vehicle near the Mos Eisley cantina has a more interesting backstory to it.
From J.W. Rinzler's Star Wars: The Blueprints (Deluxe Edition, p49).
Outside the Cantina is a space module that is an homage to the space-pod EVA from Stanley Kubrick’s 1968 film, 2001: A Space Odyssey (perhaps Mos Eisley is where astronaut Dave Bowman wound up?). Back then it was harder to find reference photos, so Lucas’s craft is not identical to Kubrick’s […]
(In an early edition of blueprints published by Ballentine in 1977, this drawing was captioned “Ubrickian Landspeeder 9000 Z001,” which reads a lot like “Kubrick 2001.”)
