58 free 2001: a Space Odyssey trivia questions with answers — entertainment quiz, new questions added Aug 2026.
2001: A Space Odyssey opened in April 1968 to walkouts, baffled reviews and a New York critic calling it 'monumentally unimaginative'. It has since topped Sight & Sound's directors' poll and is routinely named the greatest science fiction film ever made. Stanley Kubrick and Arthur C. Clarke built it from a handful of Clarke's short stories, four years of argument, and a rotating 30-ton set. This quiz covers the whole odyssey: the plot from the Dawn of Man to the Star Child, the cast and the voice of HAL, the writing and the abandoned titles, the effects work (the centrifuge, front projection, the slit-scan Star Gate), the classical music that replaced Alex North's score, HAL's real-world roots at IBM and Bell Labs, the premiere-night walkouts, the awards, and the 1984 sequel. Difficulty ranges from questions any film fan can answer to details for people who own the Blu-ray commentary. Every answer was verified against the Wikipedia articles on the film, HAL 9000, the soundtrack and the sequel, and each question shows its source.

Douglas Rain
Douglas Rain, a Canadian stage actor, recorded the computer's lines in post-production after Martin Balsam's earlier take sounded too colloquially American to the director.

Dr Heywood Floyd, played by William Sylvester, travels by Aries lunar shuttle to Clavius Base, where he is briefed before visiting the excavation.

By lip reading
By lip reading: Bowman and Poole retreat to an EVA pod to talk in private, but the computer watches their mouths through the pod window.
Q 13How does Bowman get back aboard Discovery after HAL refuses to open the pod bay doors?
He blasts himself through the vacuum into the emergency airlock
Q 21Which waltz accompanies the space plane docking with the space station?

Q 23Whose ballet Gayane supplies the mournful adagio heard as Bowman and Poole are introduced?
Aram Khachaturian
He blasts himself through the vacuum into the emergency airlock: without a helmet, he fires the pod's explosive bolts so the escaping air hurls him across the gap.

Heuristically programmed ALgorithmic computer
Heuristically programmed ALgorithmic computer is the expansion the novel gives; the authors denied that the name was a coded dig at a rival computer maker.
Q 17Fans claim HAL's name is a coded jab at which computer company that advised the film?
IBM
IBM, which advised on the film's computer displays, is one letter on from H-A-L; the writers called the match a coincidence they would have avoided had they noticed.
Q 18Which British actor played HAL on set, before the voice was dubbed in post-production?
Nigel Davenport
Nigel Davenport read the computer's lines on set during filming so the actors had a voice to play against; the part was re-recorded in post-production.
