Continuity mistake: After Slide locks Josh's boss in the master bedroom closet within Mr. Fitzhugh's ex-apartment, he turns on the boombox at a high volume. Then later in the film, when they are retrieving the car through the window of the same apartment, the music is off. Then later, Josh's boss is seen trying to get out of the closet and the music is back on.
Factual error: As an attorney, I know that one doesn't become an attorney three days after passing the Bar Exam in NY, as Miss Lovenko claims at the end of the movie. She first would have to be approved before the Character Committee, submit Letters of Recommendation of Good Character, and her background would have to be checked. If approved, she would have to wait be sworn in by an Appellate Division Judge, which is about a 6 month process, not 3 days.
Other mistake: When removing the car from the penthouse the guys decide to use the crane portion of the window cleaner's lift. The basket disappears without trace, what did they supposedly do with it?
Continuity mistake: When Jillian confronts Mr Shaw about losing the money, he flips out and eventually loses his job over damaging the car with a golf club. He demolished all the windows and tail lights. Later when they try to steal it, there is no damage and the glass is intact.
Factual error: At the end, one of the tower employees receives a gold wheel as his/her portion of the retirement program. As malleable as gold is, it is unlikely that the gold spokes in that wheel would support the car, and just gold plating wouldn't be that heavy.
