Bela Lugosi appears in footage shot just before his death, but with no script in mind. Edward D. Wood Jr. wrote the script to accommodate all the footage shot in a cemetery and outside Tor Johnson's house in the new production. Lugosi was doubled by Tom Mason, Wood's wife's chiropractor, who was significantly taller than Lugosi, and played the part with a cape covering his face.
The film's original title was "Grave Robbers from Outer Space", but, supposedly, the Baptist ministers who financed the picture objected to it, so Edward D. Wood Jr. changed it to "Plan 9".
A video release, making note of the actor's death before production began, lists on the cassette box, "Almost Starring Bela Lugosi". This same box also touted the film as being "science fiction gold".
The company was able to get police cars and uniforms through Tor Johnson's son, Karl Johnson, an officer in the San Fernando Police Department, who also makes an uncredited appearance in the film.
One of the legends about the production of this film was that Edward D. Wood Jr. used everything from automobile hubcaps to pizza pans to pie tins and even paper plates as flying saucers. The truth is that he bought a number of the Lindberg 1/48 scale "Flying Saucer" plastic model kits for use as props. One was modified with a wooden block, to represent the squared walled flying saucer set (the UFO seen landing in the graveyard).
According to Maila Nurmi, she would put on her Vampira makeup and costume at home and then take a bus to the Quality Studios soundstage where her scenes were filmed.
Much of the filming took place at an independent soundstage called Quality Studios. Though it hasn't been used as a soundstage for many years, the building still exists. It is located on Santa Monica Blvd. near Western Ave. The entranceway is located next to the Harvey Hotel.
Copies of the original 35mm release prints are extremely rare. There were reportedly fewer than 20 release prints struck for the original release. As part of the distribution deal with the Distributors Corporation of America (DCA), producer J. Edward Reynolds had to pay for the release prints and advertising material.
Contrary to popular belief, the detective that points his gun at himself several times was actually testing director Edward D. Wood Jr. to see if he would notice. Needless to say, Ed Wood didn't notice.
The DVD release of the colorized version of the film features an audio commentary track by comedian Michael J. Nelson of Mystery Science Theater 3000 fame. The producers of the series at one point actually screened the film for airing on the show, but found it to have too much dialog to fit the show's format.
After an argument with Edward D. Wood Jr., veteran makeup man Harry Thomas insisted that his name not be used in the film's credits. His assistant, Tom Bartholomew, received sole credit.
Previewed as "Grave Robbers from Outer Space" at the Carlton Theater in Los Angeles on March 15, 1957, the film went into general release as "Plan 9 from Outer Space" in July of 1959, on a double bill with the British suspense thriller Time Lock, which featured a pre-James Bond Sean Connery.The actual copyright for the film is 1957.
Leading actor Gregory Walcott was at the time a busy Hollywood contract player who attended the same Baptist church as executive producer J. Edward Reynolds.
Footage from the same shoot that produced Bela Lugosi's performance in this movie was meant to be used to make another film, "The Ghoul on the Moon". When Edward D. Wood Jr. went to retrieve the film he found it had been ruined, so the new movie was scrapped.
Although trade publications announced the movie's general release in July 1959, distributor DCA had already made prints available to cinemas from June 1958 onwards, with the film playing on regular movie theatre bills in states as far afield as Maryland, New Mexico, Ohio, Rhode Island and Texas during the thirteen months prior to its supposed 'general release'.
The cemetery used for filming is the Pioneer Memorial Cemetery in Sylmar CA. It still stands, although many of the grave stones were stolen or vandalized.
