Continuity mistake: When Dally falls off his chair in the drive-in movie theater, you can hear Ponyboy's laughter above them all. When the shot changes to Cherry, you can see Ponyboy with a serious face on in the background but you can still hear him laughing.
Continuity mistake: When Han tells Lando that he can fly the Millennium Falcon during the battle, when Lando says, "Would you get going, you pirate", his entire outfit is reversed - his shoulder holster strap goes the other way, and his rank insignia changes side too. (00:50:00)
Continuity mistake: During the scene with the guys dancing in the locker room, when the coach comes in, you see the same shot of Stefen taking off his jacket twice.
Continuity mistake: In the movie's final moments when Tom Cruise is buying back all his household items, the lady in the cargo bay says "that's everything," except for the crystal egg she throws out into the yard for Tom to catch. You can clearly see many more items left in the truck. But when the truck pulls away seconds later, nothing is left in the cargo bay except our villain sitting on a chair. Where did everything else go?
Continuity mistake: When Tony shoots Manny after he finds out that he has been with Gina, she runs to hold his bloody body, in turn getting blood on her robe. A few scenes later, when Gina comes into Tony's office, wearing the same robe, it is perfectly clean and there is no sign of any blood. (02:27:50 - 02:30:00)
Continuity mistake: In the first scene of their "training" for the big mission, the text "Somewhere near Galveston, TX" shows up as a subtitle on the screen. As it does this, there is a nice, dark aerial shot of mountainous terrain which is supposedly to hide the troops from any outsiders. The problem is, there are no mountains within hundreds of miles of the Island of Galveston. The whole terrain in this area is so flat that you can practically see from one side of the island to the other. (00:21:45)
Continuity mistake: At the end of Porky's, you see Mickey Jarvis on crutches and covered in bandages after getting beaten up by Porky. In the beginning of Porky's 2: The Next Day, Mickey has miraculously healed. He jumps out of his truck to catch up with the other guys, no crutches or bandages and he is walking fine.
Continuity mistake: Mick buys 3 cans of cola from the machine. But when he's in his room and empties his pockets, there are 4 cans. (00:48:20 - 00:49:15)
Continuity mistake: After Norman argues with Mr Toomey, before he goes up to the house, you can plainly see the light on in the living room where Mary is sitting. When Norman goes in the house, Mary is sitting in the dark and Norman then turns on the light.
