Deliberate mistake: Dr. Chandra returns to the Leonov at the end of the film with the device that Dr. Floyd designed to cut HAL's memory circuits. He hands the device back to Dr. Floyd, who tosses it in the air and catches it when it falls back into his hand. One problem - there was no gravity on the ship at the time. (01:44:00)

Factual error: In the scene where the crew members are doing a simultaneous countdown in Russian and in English, the Russian crewmember skips the number four (chetiri). She goes straight from 5 (pyat) to three (tree). (01:44:14)

Victor Milson: Millson to Floyd: It's been twelve hours since I made my request for information! I need a reply - all hell is breaking loose down here! I have enough problems without you pulling some kind of a stunt! I just hope there's an Earth for you to return to! Make that report I asked for and make it immediately.

Trivia: An interesting scene to watch is when Heywood Floyd is talking to his associate on the bench in front of the White House, there is a long shot when you can see a person feeding pigeons. It is none other than Arthur C. Clarke in a cameo appearance. (00:10:59)

More trivia for 2010

Question: In the original film, the Discovery's onboard computer states: "I am a HAL 9000 Computer, Production Number 3. I became operational at the HAL plant in Urbana, Illinois, on the 12th of January, 1992." So, "HAL" was a manufacturer identification prefix (standing for Heuristically-programmed ALgorithmic Computers), "9000" was its model number, and "No.3" was its production lineage. In this sequel, however, Dr. Chandra is chatting with one of HAL's earth-based twin computers which has a feminine voice and is called "SAL"; but how can they arbitrarily change its manufacturer identification prefix? Being produced by the HAL plant in Urbana, Illinois, and being identical to the computer aboard the Discovery, the twin's name should have a different production number, but it should still be called "HAL," should it not?

Answer: The most likely reason the name was changed was probably a literary one. It makes it easier for the audience to differentiate SAL from HAL, showing how they are two distinct computers playing different roles in the film. It may also just be a feminine nickname being that SAL has a female voice.

I thought perhaps "SAL" was a nickname, also, until I saw that the computer's maker nameplate reads "SAL 9000" (visible in close-ups of SAL's glowing eye).
