2010 (1984)

Factual error: While the Leonov has a centrifugal section to simulate gravity, the ship's bridge is not part of it (evidenced by the stationary views outside its portholes). Yet in various scenes, including the one when Floyd rushes in to discuss his plan to return to Earth sooner with Tanya, gravity seems quite evident. Floyd marches across the compartment onto the raised pilot area's floor, then steps down from it, his foot landing audibly. Tanya's open jacket also hangs down normally as she moves about. Yet when Floyd demonstrates his plan using two pens, they float in mid air. (01:26:50)

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)

Question: One thing that always confused me is why was it necessary to jettison Discovery after it was used as a booster rocket? Why couldn't they just keep it attached to the Leonov as they made their escape?
