Trivia: When the foursome ski down the mountain and are looking around at the oddly dressed people, someone behind John Cusack says, "Hey Lane, you owe me two dollars". This was a nudge to John Cusack, who played Lane Meyers in "Better Off Dead" and was pursued in the snow by a crazed paper boy shouting "Two dollars!"

Trivia: Chevy Chase makes his first appearance; he farts. This goes back to the movie Spies Like Us when he is taking the test and he farts during the test, blaming it on the guy sitting next to him. The guy says, "Excuse me," as everyone looks at him.

Mistakes

Factual error: In the scene where they are watching "The Drive", the TV is not showing an NFL game at all. The field is 110 yards long. There is an overhead shot of the field and you can see two 50 yard lines and a C in the middle. They are watching a CFL game.

Questions

Question: Considering that there are many different theories about how time travel works, such as the grandfather paradox, temporal paradox, etc., why did Adam assume that the butterfly effect was the primary rule of time traveling?

Answer: It's just the rule they used for the movie; not a lot of thought was put into the time-traveling rules with the obvious inconsistencies the movie has throughout regarding it, especially in the ending.
