Factual error: There is a scene in which Piter DeVries is talking about the Landsraad (one of the governmental organizations in Dune). Twice he mispronounces the name, saying "Lansdraad" instead.

Mistakes
The Fremen wear "stillsuits" to conserve their water, yet leave their heads completely uncovered. This would result in quite a bit of water loss through perspiration. (In the book, they wore hoods, masks and nose filters, leaving only the eyes uncovered, but it wouldn't work in a movie to have all the actor's faces obscured!). See more...
Trivia
The TV version of this film lists a Mr. 'Judas Booth' as the screenwriter. Allegedly this was to get back at David Lynch (who was both screen writer and director) for so brutally condemning and demanding that all credits to him be removed from the film's re-edit for TV. The name is a combination of Judas Iscariot, the betrayer of Jesus, and Abraham Lincoln's killer, John Wilkes Booth. See more...

Dune mistakes
Continuity: Depending on the version, in the final confrontation between the Emperor and the Harkonnen, and Paul and the Fremen, you can see Thufir Hawat standing in the crowd of the imperial side. After the battle between Paul and Sting he has suddenly disappeared. This is due to there being different, much longer versions of the same film. There is a 120 minute version, 180 and 190 minutes, and apparently in Singapore you can buy a 240 minute version. However, in the long versions the stains on Thufir's lips and Paul's totally blue eyes do not appear in the extra scenes: now you see it, now you don't.
Revealing: During the invasion of Dune by the Harkonnen, a Sardukar soldier throws a guard from what appears to be the palace's wall. When he hits the ground all the bodies around him bounce as if they where lying on some sort of cushion.
Dune trivia
The tendons on the worm when it gets hooked by Paul are made from condoms.
David Lynch was disgusted with the elongated cut of the film which includes paintings of the 'robot revolt' back story to the original film, a sub-plot he deliberately omitted. He demanded his name be removed from the credits of the film and replaced with the Director's Guild nom de plume, 'Alan Smithee'. This was done so sloppily, by superimposing Smithee's name over Lynch's, that the credit reads "A ALAN SMITHEE FILM".
