One scene called for Duke Leto (Jürgen Prochnow) to be strapped to a black stretcher and drugged. During one take, a high-powered bulb positioned above Prochnow exploded due to heat, raining down molten glass. Remarkably, Prochnow was able to free himself from the stretcher, moments before glass fused itself to the place he had been strapped. During the filming of the dream sequence, the Baron (Kenneth McMillan) approached Leto, who had special apparatus attached to his face so that green smoke would emerge from his cheek when the Baron scratched it. Although thoroughly tested, the smoke gave Prochnow first and second degree burns on his cheek. This sequence appears on film in the released version.

Director David Lynch and producer Raffaella De Laurentiis arranged a screen test in New York with Sean Young for the role of Chani. Young's agent never told Young about the meeting, and she was in fact booked on a flight that evening to Los Angeles. Lynch and De Laurentiis missed their flight back to Los Angeles, and ended up catching the same plane as Young. During the flight, De Laurentiis noticed Young and told Lynch, "I bet that girl's an actress." A stewardess told the pair that her name was "Sean Young", and De Laurentiis confronted Young about standing him and Lynch up. The misunderstanding sorted out, the three ended up drinking champagne and reading the script together upon returning to Los Angeles.
The name "Judas Booth" that appears as the screenwriter in the extended TV cut, is a combination of Judas, the apostle that betrayed Jesus Christ, and John Wilkes Booth, Abraham Lincoln's killer. With this in-joke, David Lynch meant that the studio betrayed him and killed the film. The director's credit is the usual in these cases Alan Smithee.

Alejandro Jodorowsky had originally planned on filming Dune in the early-'70s, and had enlisted the help of Jean Giraud and H.R. Giger to create the movie's visual style. Salvador Dalí was enlisted to play the part of the Emperor, and Jodorowsky also intended to cast his own son Brontis Jodorowsky as Paul, David Carradine as Duke Leto, Orson Welles as the Baron, and Gloria Swanson as the Benne Geserit Reverend Mother. The soundtrack was to be done by Pink Floyd. According to Jodorowsky, "The project was sabotaged in Hollywood. It was French and not American. Their message was 'not Hollywood enough'. There was intrigue, plunder. The storyboard was circulated among all the big studios. Later, the visual aspect of Star Wars (1977) strangely resembled our style. To make Alien (1979), they called Moebius [Giraud], Foss, Giger, O'Bannon, etc. The project signaled to Americans the possibility of making a big show of science-fiction films, outside of the scientific rigor of 2001: A Space Odyssey (1968). The project of Dune changed our lives." Jodorowsky also planned on making numerous changes to the source material, including making Duke Leto a eunuch and the spice a blue sponge. Author Frank Herbert openly despised these concepts.

David Lynch (13 January 2006) : "Dune I didn't have final cut on. It's the only film I've made where I didn't have, I didn't technically have final cut on The Elephant Man (1980) but Mel Brooks gave it to me, and on Dune the film, I started selling out even in the script phase knowing I didn't have final cut, and I sold out, so it was a slow dying- the-death and a terrible terrible experience. I don't know how it happened, I trusted that it would work out but it was very naive and, the wrong move. In those days the maximum length they figured I could have is two hours and seventeen minutes, and that's what the film is, so they wouldn't lose a screening a day, so once again it's money talking and not for the film at all and so it was like compacted and it hurt it, it hurt it. There is no other version. There's more stuff, but even that is putrefied."
