I hate this scene. It spoils the Jabba scenes in Jedi.
Also, it feels it shouldn’t even be there. I was really glad that Lucas or someone cut that out in 1977.
I think the editors cut it out. They completely recut the film to fix the horrible pacing problems. It seems like I heard that Greedo’s subtitles were used to change his dialogue after the seen was shot so they could put some information from the Jabba scene there.
I think Lucas was going to just have Jabba be a man (not that he might not have planned on making him an alien before it proved to difficult) but that the editors got rid of the scene because it was pointless and slowed the movie down.
There was a reason the film won best editing but not best director.
