To truly get that “degenerate” vibe, intercut some hardcore STAR WARS porn scenes into the Jabba’s palace and sail barge scenes. Gotta have some sex scenes in there to go with the drunken revellers.
Ah, the Guccione’s Caligula route!
My suggestion would be to add that movie’s Lawnmower of Death to Jabba’s Palace. It’s way more effective than the Sarlacc.
