 Several bits from the trailer do not appear in the finished film.  These include Nancy pulling a gun on Jack (and the resulting dialog  of her asking, "What kind of girl do you think I am?" with Jack  replying, "The kind of girl who had a gun on me thirty seconds ago,"  and Nancy saying "Yeah, but I didnt SHOOT you..."); Nancy and Jack  actually getting into the car as they steal it (she playfully says,  "Lets make out!" and Jack replies, "Eaaasy..."); a couple shots of  Jack and Nancy kissing; Jack and Nancy on a skateboard; and finally  Jack making a playful growling sound.
