An old Quote-
it's more interesting to note that the character Captain Antilles is never identified on film. Aside from a mention of C-3PO having been owned by a man of that name, there's nothing. Fans assumed that the man being strangled (designated in the shooting script as "Rebel Officer"😉 was the owner of the ship and the captain, and it would make sense that the droids were his. In the Radio Drama released several years later, it was later revealed that he was the Captain Antilles C-3PO was talking about. In the novelization, his name is Captain Colton
