I was thinking that LFL had some budget cuts when make ROTJ because the sets looked like they are lacking in budget, but ROTJ had the highest budget of the three OT. Star Wars had a budget of just a little under $ 10 mil, ESB ended up being about $20 mil, and ROTJ had a budget of about $32 million.

I guess a lot of it went to bloated advertising like the prequels.

Another thing that makes me think ROTJ had a low budget was that it kinda ends abrubtly. In like the last 10 minuets everything comes to a conclusion and then WHAM! it's the ending. I think the movie should've taken a little slower pace towards the end and I don't like the direction GL took with the revisions, having all the stupid celebrations at end with Jar Jar Binks saying "weeza free!!!"
