Seeing shadows of Anakin and Padme when they're outside Lars' house
Padme is knocked out when Dooku's ship is found in a hangar, but when she wakes up she mentions the ship's destination, which she wouldn't have known
On planet Tatooine, Padme is seen pressing a
button, then moments later presses the same one to carry out a totally different function
The same background of flying ships can be seen repeating over and over again while Palpatine is talking to the Jedi Knights near the start of the film
Jon Sandys, who runs the movie mistakes site, said: "It's not about criticising movies, just a list of all the things from your favourite films you'll be amazed you missed and might have fun spotting."
