Obi-Wan Kenobi: [To Anakin.] Why do I get the feeling you're going to be the death of me?
When Amidala & Anakin are eating and he cuts her a piece of the fruit and "floats" it back to her, the bite appears in the fruit a split second before she actually eats it.
The first scene in which Obi-Wan and Anakin appear was filmed after principal photography had finished. Ewan McGregor had shaven off his beard, so he had to wear a fake one.
