Continuity mistake: You can't even see inside because of all the smoke (fog) when Dante pulls up to Moobies after he went looking for Becky. But 90% of the smoke (fog) is gone as soon as he walks in the door. You can *easily* see outside the windows in the rest of the shots. There's not nearly enough time for the smoke (fog) to evaporate.
Continuity mistake: Becky is holding the bottle of nail polish by the sides of the lid, bottle parallel to her hand, when she first holds it out to Dante (over her shoulder shot). The next shot is from in front of her and she's holding it by the very top of the lid, hand above the bottle. It's a quick shot change and she doesn't have enough time to re-position her grip, yet she does, and she didn't just rotate her hand, her fingers move a good inch up the side of the lid.
Factual error: Dante's last day seems to be in the fall season, judging by the amount of leaves on the road when he and Randal drive back from the Go-Karts. One of the last scenes is of all four of them outside the just re-opened Quick Stop and you can see that Becky is very much pregnant (at least 5 months) but the season is still the same (look at the trees). There should be snow on the ground in NJ at that time (Jan-Feb), or at least it would be cold enough to wear a coat and see your breath.
Continuity mistake: Becky's bra strap and shirt strap gap in the front and meet in the back during the scene where she's asking Dante if he's afraid to get married (most easily viewed during the over-her-shoulder shots). The straps align and are on top of each other when she leans forward when Dante tells her that he can't dance. All subsequent over-her-shoulder shots still have the straps in the same position as before she leaned forward.
Revealing mistake: When the Quickstop burns down in the beginning, you can easily tell the fire has been added with computer graphics, as it appears very flat, and some even has a slight blue haze around the outside, where a little bit of the blue screen "bled through."
Continuity mistake: When Dante is sitting on the firetruck in the opening scene, after witnessing the burning of the Quickstop, you can see the same 2 firemen walking by him in the wide shot, and then immediately again in the closeup. (You can tell easily tell, as one is holding what I think is an axe.).
