Continuity mistake: In the scene where Belushi and Jerry Lee (the dog) enter the warehouse, Belushi askes everyone to stop what they are doing and even has the forklift driver lift him up so he can talk to them. Once he is done talking, he tells the lift driver to bring him down. The next few shots where they show Belushi walking to his car, if you look closely, you will see that the fork lift is back up in the air, but there were no sounds and there isn't another lift to be found.
Continuity mistake: When the Lyman realises that Dooley's bomb detonator is a fake, he starts running away. He must be some sprinter, because in the first shot he's at the end of the semi trailer, and in the next shot he's a good 400m away. He simply could never have gotten that far away in a split second.
