Dr. Jackson (James Spader) says disdainfully that the translators have obviously been using Budge, and wonders why "they keep reprinting him". He is referring to noted Egyptologist Sir E.A. Wallis Budge (1857 - 1934).
Jaye Davidson despised the costumes he wore so much, on the last day of shooting his scenes, after hearing the final "cut", he stripped naked on the set without going to his trailer. Moreover, Davidson retired from acting after completion of this film. Since 1994, as of 2010, he has only appeared since in The Borghilde Project, a 17-minute film.
Theatrical trailer and promo reel found on the European DVD (distributed by Kinowelt/Momentum) include extensions or snippets of additional scenes which are neither included in the theatrical cut nor in the special edition version of the film: - one of the guards appears behind Sha'uri and Daniel. This is presumably from the scene where Sha'uri gets shot - when Sha'uri is in the sarcophagus, Ra holds his hand above her - a different take of the scene where Ra punishes his guard. Here Ra is seen from the side - village scene at the beginning is longer - longer entrance of Ra at the assembly. O'Neill and his men are pushed down by the guards - extended entry to the control room. Daniel gets an explanation of how things work. You see that the conference room is directly above the control room - extended activation of the Stargate. You see more of the two technicians operating the Stargate. General West orders final evacuation. The two technicians leave the control room. O'Neill looks back at West. West leaves the conference room and the shutters close
Roland Emmerich and Dean Devlin were sued for stealing the storyline from a student of Egyptology named Omar Zuhdi who submitted the story to them about ten years before the movie was made (they "rejected" the story at the time). Zuhdi even had a well-respected Egyptologist from Johns Hopkins University vouch for him, since he put his own theories into the story. The only differences between the story and the movie are slight name variations. The issue was finally settled out of court.
Jaye Davidson's dislike of the attention that he received after The Crying Game made him reluctant to take the role of Ra in Stargate. He didn't want to just turn the offer down so made what he expected to be an unacceptable demand of $1 million. This was accepted and he appeared.
As it happens in Mexico with most movie titles translated from English, the title for this movie was "La puerta del tiempo" which translates to "The Gate of Time". Some moviegoers mistakenly thought the far away planet the squad goes to was just a very early time in Egypt, and were seriously confused with the storyline.
The early pre-release screenings of the movie were disastrous. The percentage of the audience who liked the movie fell into the mid-30's, and executive producer Mario Kassar realized the main problem was that the plot made zero sense. His solution: have the Ra character's dialogue subtitled and made into information that presented a clear storyline. When these changes were made, the subsequent test screenings produced an overwhelming majority of positive reviews, and this carried the movie into becoming one of the surprise hits of fall 1994.
Although the planet visited through the Stargate is never referred to by name throughout the length of the movie, its spin-off TV series Stargate SG-1 would later reveal the planet's name to be Abydos.
Ra's former host's race was never identified throughout the movie. While the TV series Stargate SG-1 would later identify the entity of Ra as a Goa'uld, his former host was still never identified, but it does bear a strong resemblance to the Asgards (Thor's race)--so much so that the Stargate SG-1 Roleplaying Game would even go on to identify Ra's former host as an Asgard known as "Famrir".
In a magazine interview, James Spader said that he found the original screenplay "awful" but also that it was so bad it actually intrigued him. He then met with Roland Emmerich, was inspired by the director's passion for the project, and decided to make the movie because he felt the energy and craziness of making such a film would translate into an exciting final film.
One of the skeptics at Daniel Jackson's lecture asks who built the Egyptian Pyramids: "Men from Atlantis? Or Martians, perhaps?" Given the plots of this movie, Stargate SG-1, and Stargate Atlantis, he was, in fact, correct on both counts.
The trivia item below may give away important plot points.
The eye glowing effect that Ra has was actually added in Post Production because the test audiences didn't think that he was alien enough. This trait was continued in Stargate SG-1 as an identifier to people who are taken over by the Goa'uld.
