Continuity mistake: Just as the Presidents have bumped the door into Tabitha and said "...we're all counting on you.", you see Cody, Cindy and George standing with their backs to the trapdoor. When it cuts, they are standing with their backs to an opposite wall. (01:10:00)
Continuity mistake: When Tabitha falls down the well Cindy, George and Cody is looking down after her. When it cuts to the water splashing up from the well George is holding Cody and covering his eyes. (01:10:10)
Continuity mistake: After George has closed the well, the alien appears. Cody and Cindy gasp, and you see Cindy putting her arm on Cody's right shoulder. George climbs up from the hole and puts his hand on Cindy's shoulder. When it cuts, Cindy's hand is on Cody's left shoulder and George's hand is on Cody's right shoulder. (01:10:20)
Continuity mistake: When the alien says goodbye to George, Cindy and Cody, you can see both Cody and Cindy holding their arms down. When it cuts, Cody has both his hands up waving at the alien and Cindy has one arm up waving. (01:10:35)
Continuity mistake: During her wedding, Cindy throws her flowers over her head and we see a group of women dive for them. However, in the next shot, the President emerges from the pile-on with the bouquet, even though he was not in the pile-on originally. (Regardless if the intention was to surprise the audience, this is still a continuity error.) (01:11:05)
Visible crew/equipment: After Cindy and George are married, As the shot zooms in to the 'Just Married' sign, you can clearly see crew members reflected on the boot of the car. (01:11:10)
Continuity mistake: At the very end of the movie after the wedding, Cindy and the other guy drive off, leaving Cody behind. We see the boy running after them along a straight road. After Cindy stops short of striking the child, Cody is then hit by another car coming from his right hand side and they're suddenly at a crossroads. They weren't at the crossroads a couple of seconds earlier. (01:11:30)
Continuity mistake: At the end when George is backing the car against Cody, watch Cody's hand and facial expression. They change remarkably during the three different shots of him. (01:11:35)
Continuity mistake: When George and Cindy are driving along, after getting married, if you look out the back window, you can see Cody is not on the road. The camera cuts and he is. (01:12:40)
Audio problem: In the Michael Jackson scene when the guy is holding him out of the window, most of the time when he's screaming, his mouth is closed.
Continuity mistake: After talking to Cody outside of the school, it shows Cindy pulling away. A few feet away, you can see a blue trash bin, as well as a blue banner hanging from a building. Inside the car, Cindy pulls a few feet away way from those two things. However, after she notices Cody is not in the car, it goes outside the car again, and Cindy is shown at the same place as before, but did not move there.
Continuity mistake: When George is going to his rap battle, when he gets on the bus and the doors close on his face, his hat falls off, but when the scene cuts and shows him again, his hat is on.
Revealing mistake: As the one alien talks, look behind him. The seam where the two halves of the alien head prosthetic is visible on the second alien.
Revealing mistake: As the alien grabs George, the alien's finger bends backwards at an impossible angle, showing it's a glove. Also, the right eye of of the next alien is half way open, partially revealing the actor's eye.
Revealing mistake: When George comes flying out the window at Brenda's wake, if you look at his face, you can see it's a stunt double.
Continuity mistake: When Cindy is picking up Cody at school, right after George leaves the classroom, we see crayons get thrown at the door. Its supposed to be one of the students who threw them, but if you look at the arm in the shot it's an adult arm.
Continuity mistake: When George hits Cody with the basketball and just before he runs to help him you can see Cindy putting her coat on but when George kneels down to help Cody she is gone through the whole shot till he runs back to her.
Continuity mistake: When Cindy is talking to the Oracle about the tape (the shots right after the Oracle ruins the Lakers game for Morpheus) if you watch the Oracle's hand on the right it changes positions.
Continuity mistake: When Cindy is watching the tape she found at Brenda's house the lava lamp behind swaps to a normal lamp and then back to a lava lamp, between shots.
Answer: It was an alien in a Michael Jackson skin. He shed it and ran off into the bushes.
