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: When Dan walks down to a podium and looks over to see the dolphin knocking at the gate, the tee-shirt he is wearing changes from being plain white with a tag badge on his left, to a white shirt with a large blue stripe across it, with a tag badge being on the right. (00:08:20)Hamster
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: Mention is made that Pamela owns the brewery because she has just turned 21. During the scene with the video game, she says her birthday was October 21, 1959. Later, the lawyer for Bob and Doug establishes the movie's timeframe by mentioning her kidnapping on October 10, 1983, which would make Pamela almost 24 years old instead.
