The voice is definitely different here than in most of the televised versions of "The Saga." The others are clearly Brando, but here it sounds like someone imitating Bogart! (I also found the variant voice in the Bravo TV version from 2007.)

What could account for using a different audio track here? Some damage to the original material? Did a stand--in read those lines during filming and somehow it got left in some prints? Fascinating.
