Star Wars: Episode III - Revenge of the Sith

George Lucas deliberately made the Darth Vader suit top-heavy (for instance adding weight on the helmet) to make Hayden Christensen not appear "too accustomed" to it in the movie.

When Padmé is trying to convince Anakin to turn from the dark side on Mustafar, Anakin says "And I'm doing it for you, to protect you," but his mouth says "And I'm doing it because I love you, to protect you."

The opening logo for 20th Century Fox is static (to match the opening of Episodes 4, 5 and 6), instead of the animated 3-D logo used in Fox films at the time.

As Obi-Wan leaves Mustafar, there is a shot of him sitting in the cockpit of Padme's Naboo skiff, with C-3PO sitting next to him. The next shot is of the badly burned Anakin trying to claw his way up the lava bank with his remaining prosthetic arm. In the theatrical version, these shots were separated by a wipe. In the DVD, it is a normal cut. But in the 2011 Blu-Ray release, the wipe has been restored.
