Then the director changed his mind. “We had some difficulty deciding exactly what HAL should sound like, and Marty just sounded a little bit too colloquially American,” Kubrick said in the 1969 interview. Mr. Rain recalls Kubrick telling him, “I’m having trouble with what I’ve got in the can. Would you play the computer?”
Interesting that Christopher Nolan, who is well known as a Kubrick fan, made Case and Tars in Interstellar sound colloquially American.
