Other mistake: Just before the evil robots capture Bill and Ted's girlfriends, after they crash through the window, the girlfriends ask the robots: "Who are you?" and Bill goes "Well, I'm really Evil Ted!" and unzips himself and out pops Evil Ted, and the other robot goes, "And I'm really Evil Bill!" and out pops Evil Bill. When the robots are herding the girlfriends out just before knocking them out with their breath, you can see two sets of clothes in the bottom left corner if you watch closely.
Other mistake: There is a man and a woman who do the voices on the radios Leon listens to at Game Control. The man also does the voice for 530 AM at the airport, while the woman does the voice for the airport intercom, first noticeable when the White Team arrives at the airport. The woman then does the voice of the hotel operator, "Paging Mr. Player." These two are very busy indeed.
Other mistake: In the scene where Alyssa's father is in her room, she says "Ms. Kensington seems nice. Does she work with you?" Then she holds on to the bedpost and sort of swings herself around it while looking up at the ceiling with her tongue to one side of her mouth-she probably thought it was just a practice shot. She does the same thing in the scene where she is on the pottery wheel with Diane-she quickly looks up towards the camera.
Other mistake: Every person in the movie has exactly the same make and model of computer with exactly the same desktop configuration on it. The number, type and order of icons is the same, as is the plain blue background. (00:30:50 - 00:31:40)
Other mistake: When Josie just arrives to the school and is standing with her back to the car, we see a blonde girl with a short blue dress pass, in the next shot, she passes again. (00:14:55)
Other mistake: Watch when two bodyguards shove Mel and Val towards the car at the end of the movie- one of the bodyguards steps on Val's tail and nearly trips.
Other mistake: When the priest is singing to himself in the garden, you can hear a person off camera say "go" just before the mayor enters.
Other mistake: For the entire length of the movie, Bam Magera is referred to as Bam. But in the credits, his character's listed as Chad.
Other mistake: When Scooby and Shaggy are in the cafe, Shaggy says "Can you believe the cafe ran out of food but we're still hungry." But we can see food behind the counter.
Other mistake: When Brian is being chased by people who believe he is the Messiah, Brian loses a sandal. They all think it's a sign and run after him with one sandal in their hand. Thing is, when you see them, thay all have both sandals on their feet, yet most of them are holding a sandal. Where did they all get their third sandal from?
Other mistake: In the scene where Chris & Bill are about to bug Maria's phone, she is talking to her mom on the phone & Chris is on the telephone pole listening in. You can hear her talking but not her mom.
Other mistake: In the scene on Christmas morning before the party Ann and Adell are talking on a phone with a cord, Ann is sitting on the bed on one side of the room holding the receiver with the cord leading to the side of the room across from them, next to the TV. But when it shows a shot of the TV, the same phone that Ann is talking on is hung up sitting next to the TV.
