Continuity mistake: At the start of the movie, the guys are in an LTD chasing a Greyhound bus so Tom Cruise can get on. They pull ahead of the bus and pull over to stop. The bus stops really close to them almost hitting the LTD. In the next scene they get out of the car and have to walk about 20 feet back to the bus.
Continuity mistake: Elizabeth's character, Jordan, meets Brian on one day. Then the very next day (looks to be around noon or so) she comes to thank him for helping out yesterday. That evening, she and Brian go with Doug and Kerry to a club where she answers Kerry's question of "How long have you known him?" by saying "About 10 hours."
