Disney asked that the budget be cut by approximately twenty million dollars, and when the film was released on Christmas Day, it flopped at the box-office. Robin Williams blamed Disney's marketing, and the loss of content the film suffered because of the budget cuts. As a result, he fell out with Disney again.
The aria that Andrew is listening to when he first uses the record player is from Dvorak's opera "Rusalka." The opera is concerned with the fairy-tale story of a water nymph who wants to become mortal for love.
Before Chris Columbus worked with Robin Williams on Mrs. Doubtfire (1993), he had seen him in comedy clubs in Los Angeles where he was blown away by his energy. He thought him one of the most impressive minds in terms of comedy. On stage, he was an impressive ball of fire.
In the original "Bicentennial Man" story by Isaac Asimov, the robot manufacturer was named "U.S. Robots and Mechanical Men". Around 1971, a new modem-manufacturing company took the name "U.S. Robotics", partly to honor Asimov. Unfortunately, since in the movie the robot manufacturing company is not portrayed positively, the real-world company asked the filmmakers to use a different name. Hence, "NorthAm Robotics". There are a few places in the film where you can see the old name and logo.
Third and final collaboration between Robin Williams and Chris Columbus, which started with Mrs. Doubtfire (1993), and Nine Months (1995). A plan to do a sequel to Mrs. Doubtfire had to be canceled after Robin Williams's death.
Sir's actual name (revealed when he and Andrew go to NorthAm Robotics for the first time) is Richard Martin. Miss and Little Miss are named Amanda and Grace. When "Sir" and "Ma'am" are sitting on the bench in the yard, you can hear him say, "Rachel," and since the girls' names are revealed, this can be seen as "Ma'am's" name.
The story that inspired this (Isaac Asimov's "The Bicentennial Man") was originally a novelette that was published in 1976 as a part of Asimov's "Robot" series and won both a Hugo Award and the Nebula Award that year. It formed the basis for the novel "The Positronic Man" which was written by Asimov and Robert Silverberg and published in 1993.
In the beginning of the film, the older sister mentions that Kate McAllister's family also owns an android. This is almost certainly a reference to the family of Kevin McAllister from the first 2 Home Alone movies, which were directed by Chris Columbus, who also directed this film.
Chris Columbus later admitted that although he wanted to direct the film to work in science fiction for the first time, the production ended up being more work than he was ready for and there should have been a different director.
The motorcycle used in the film is the Motó 6.5 designed by the famous French industrial designer Philippe Starck in 1995 for the Italian motorcycle company Aprilia. It's slightly modified to look more futuristic.
In this movie, Andrew (Robin Williams) is bound by the Three Laws of Robotics. Five years later, Robin Williams' character was also bound by the three codes from The Cutter's Code in The Final Cut (2004).
In one scene, Amanda teaches Andrew to play the piano. In the British science fiction sitcom Red Dwarf (1988) the character Kryten, who like Andrew, is a robot that serves humans, is taught to play the piano by Ace Rimmer, which happens off-screen, but is mentioned.
When Andrew walks up to Portia and Lloyd at the hospital and finds Little Miss has had a stroke, Portia appears to be wearing two different shoes. One is a stiletto (left foot) and the other shoe appears to have a boxed type of heel (right foot).
There are similarities between this film and Mrs. Doubtfire. Both movies are directed by Chris Columbus, and have Robin Williams in the lead role. Both movies are comedy-dramas and are rated PG-13. Both movies are filmed and set in San Francisco, California. Both lead characters undergo transformations to fuel their agenda, e.g., Andrew becomes more and more human and Daniel dresses up like an old woman to see more of his kids, since he's divorced. Both struggle to get what they want (e.g, Andrew's rights for his humanity, and marriage to the granddaughter of his owner, and Daniel's rights as a divorced dad to see his kids more than on Saturday), and are at first denied it by a biased old congress president and court judge. Both fight again for their rights and get what they want. In the end, Andrew grows old and dies a happy bicentennial man and Daniel lives and spends time with his kids again.
