Delayed filming
While filming a complicated scene at Jabba The Hutt’s palace, Carrie Fisher had to wear one of her more revealing costumes. It was a type of bikini that she wore while held prisoner under the gangster Jabba The Hutt. Apparently, it was not an easy piece of clothing to wear and constantly needed adjustment.
This was also due to the fact that Carrie Fisher did not want to let the costume designers help her keep the outfit together. For some reason, she rejected the tape they had prepared for her and shot without it. They had to redo the scene so many times because of wardrobe malfunctions, it set the schedule back.
