Continuity mistake: When Gwen is watching the soap opera Santa Gruz, together with Eddie, in the front shots of the TV screen, you see a video cassette on the top of the TV with the heading "SONY". But, in the side shots of the TV screen, you see that the same video cassette is turned. (00:58:45 - 00:59:45)
Continuity mistake: When Andrea, Gwen and Eddie watch the soap, in the wide shot of the TV we see the wall behind it. In the close-up of the TV, the screen is much higher in relation to the wall, the two notices on the right are not taped next to the window frame, the tapes lying on top of the TV differ and there is no book on the TV stand in the wide shot. (01:02:05)
Factual error: The sight of Andrea's body after she died of a heroin overdose should have been much more graphic. She wasn't foaming at the mouth, there were no needle tracks on her arm, and the cut she made on her leg a few days prior to her death is no longer there.
Deliberate mistake: When the limo driven by Gwen (Sandra Bullock) runs over the white picket fencing it's not Sandra's face behind the wheel in the exterior shots. Also, when Gwen runs over the short white picket fencing, in the interior shot from the car the corner of an 'L' shape fence is being hit, then in the front exterior shot the end of a smaller fence is hit. This is cut from a longer sequence, the smaller fencing is seen way in the distance in the first shot. (00:07:45)
Continuity mistake: When Gwen comes into the bridal suite, between her front and back shots, her pink shoulder straps change position, the amount of champagne in the glass changes, the white cloth in the ice bucket isn't in one shot. The sunglasses on her grey bag disappear when she reaches into her bag and the bouquet with the ribbon, under her arm, changes too. (00:04:20)
Continuity mistake: When they go into the drugstore and Eddie asks for the key to the men's room, his sleeves keep changing from being up at his elbows, to down by his wrists.
