In the novel of 2001: A Space Odyssey by Arthur C Clarke, published in 1968, in Chapter 25, Bowman asks Poole to wave at him to signal he is alive after his collision with the pod during his spacewalk. Poole waves but we then read the following sentence
"Poole's gesture was an echo of Captain Ahab's when, lashed to the flanks of the white whale, his corpse had beckoned the crew of the Pequod on to their doom"
Poole is dead and his gesture is due to the random motion of the pod.
Captain Ahab is the central character in the novel Moby Dick but it is not Ahab in that novel who ends up lashed to the whale, it is a character called Fedallah. Ahab is snagged by a rope and dragged violently and quickly underwater to his death. In the 1956 film by John Huston, with a screenplay by Ray Bradbury, Ahab's fate is changed to incorporate that of Fedallah and is exactly as Clarke describes in the novel of 2001. Note that there is no reference to Moby Dick in the film of 2001. You can see the relevant scene from the John Huston film below
So my question is was Clarke deliberately and knowingly including this reference to the film version of Moby Dick because it had a connection to another science fiction author or had he simply not read Moby Dick and did not know any better?
