Revealing mistake: After the final battle scene when the Jedi council come down to the Naboo city, as they are leaving the spacecraft there is a figure in the background who is obviously supposed to be Mace Windu, but is definitely not Samuel L. Jackson. The man is African-American, bald and dressed in Windu's clothes, but is not him. Perhaps Mr. Jackson was unavailable that day. (02:00:50)
Suggested correction: There is no indication that this man is "supposed to be" Mace Windu. First, several adult Jedi wear similar clothes. Second, during the funeral service for Qui-Gon, there are two rows of people sitting in a large, round room. We don't see all of them on screen. No reason why another human Jedi, who looks similar to Windu, could not be there.
