In April 1968 an audience in Washington watched a computer calmly decline an astronaut's order, a scene that split critics and left the film in the red. The episode looks at how the flat voice of HAL was made, and at how far the movie machine sat from real 1968 computers: card decks, tape reels and a remote teletype.

Still debated
Whether HAL is conscious is never settled by the film, and whether its famous ambiguity was designed or salvaged by the late cuts remains open. The critical split is often retold as critics simply getting it wrong, but they disagreed with one another.
