After the movie was released in French-speaking Canadian regions as "Woody and the Robots", Woody Allen inserted a clause in all of his subsequent contracts that his movies' titles could not be changed by other parties.
Woody Allen originally intended the film to be three hours long, and in two parts. The first part would have him in the present day, coping with life, until his illness. And the second half, would be the futuristic part. But, United Artists rejected this concept.
Woody Allen had originally hoped to shoot much of the film in Brasilia, Brazil's futuristic capital city complex designed by urban planner Lucio Costa and architect Oscar Niemeyer. Budget limitations however restricted him to using locations within the continental USA.
Woody Allen confirmed the scientific feasibility of his screenplay ideas in a single lunchtime meeting with Isaac Asimov. Allen also consulted with leading science fiction writer Ben Bova to make sure that some of his futuristic predictions were feasible.
The rebel hideout was filmed at "the Sculptured House", a residence designed and built by architect Charles Deaton in the mountains west of Denver. The home was constructed in 1963 but the interior was not yet complete at the time of filming. In 2004, the home was offered for sale for $10 million.
The exteriors for the beige building in which Woody Allen's character lives (and where the nose is destroyed) were shot at the National Center for Atmospheric Research (NCAR) Foothils Laboratory in Boulder, Colorado, USA.
The exploding bowl of "instant pudding" in Luna's kitchen was created live on the set by mixing together two liquids that reacted to create polyurethane foam. The technique is commonly used for spraying insulation inside buildings.
This film permanently ended plans for two productions based on H.G. Wells' "When the Sleeper Wakes", the 1899 novel on which this film is loosely based. One proposed production was by American International (long shelved due to the high proposed budget) and the other by producer George Pal.
Comedic character actor George Furth makes and uncredited appearance as one of the guests at Luna's party. Furth, who was Jewish is wearing an inverted Nazi Swastika on his chest, which he contrasts by wearing a Tallit, a traditional Jewish prayer shawl complete with fringes, over it.
At about 1:03 Miles is passing a 23rd Century McDonald's indicating "Over 795,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000,000" Served." If translated into American numeration this value would be Seven Hundred, Ninety-five sexdecillion," a value with 51 zeroes. By comparison, Avogadro's Number, 6023E23 (or 6.023^23), or "mole," is a value normally used to count atoms or molecules, and, incidentally, thought to be about the number of grains of sand on all the beaches on earth, give or take a couple orders of magnitude. The value of 795 sexdecillion is very nearly a mole of moles.
Woody Allen and rock star Alice Cooper happened to meet while staying in the same hotel while Allen was filming and Cooper was on tour. Allen invited him to the set to watch the filming, but Cooper did not appear in the film.
According to editor Ralph Rosenblum, Woody Allen filmed and then deleted a fantasy sequence in which Miles plays a game of chess with life-sized chess pieces, and is then sentenced to death by the chess pieces after he loses the game.
Miles is shown a clip of _Howard Cosell_ providing sports commentary to identify. It is suggested that being forced to watch such footage was used as a form of criminal punishment (which Miles confirms to be correct). _Howard Cosell_ had previously played a bit part in Woody Allen's Bananas (1971) where he interviews the Dictator toward the end of the film.
