RogueLeader brings out a really good point about the whole thing. Luke grew up on Tatooine and knew all about Jabba … which in turn probably would have heard about Jabba and his Sarlac executions … The only way out of the palace is that way with everyone. Hmmmm…

I think there is plenty of a data base with Anthony Daniels to dub in an extra 3PO line. I also agree trimming the Rancor scene a bit is good too to make it feel more like “part of the plan.”
