Star Wars: Episode VI - Return of the Jedi

Carrie Fisher really cared about Warwick Davis' well-being during filming, as he had to spend it in a hot Ewok costume. She also provided him with cookies and chocolate milk between takes. Davis later commented "She was everything an eleven-year-old Ewok could possibly wish for."

When Vader throws his saber at Luke who is hiding on the catwalk in the Death Star, Vader's saber blade is coming out of the butt end of the hilt - not the proper blade end.

To compensate for the longer credits, later versions of the film like the special edition and DVD release extend the piece of musical score that plays over the credits.

The Special Edition slightly re-edits the closing on Endor. Originally, there is one medium shot of the ghosts of Anakin Skywalker, Obi-Wan Kenobi and Yoda, followed by Luke rejoining his friends, and then another long shot of Anakin, Obi-Wan and Yoda. For the special edition, the medium shot is split in two, so that the first medium shot is shorter, and ends with Obi-Wan looking down at Yoda, then cuts to Luke rejoining the rebels, then cuts back to the rest of the medium shot, before cutting to Luke, and then finally back to the long shot of the ghosts.
