Corrected entry: In one shot of Grace having sex with Jake, underwear is visible on her hip. (01:43:25)
Corrected entry: While Grace is talking to Bobby on the phone she is holding a pack of cards. In some shots the 2 of clubs is on the bottom, in others the queen of spades. (01:18:30)
Corrected entry: When Bobby Cooper comes back to Grace McKenna's house near the start, he puts his bag on the side. They're eventually disturbed by Jake McKenna, Cooper gets punched in the face and legs it, leaving his bag in the house. We then see him walking along the road back to town with his bag, which he's magically got back.
Correction: This may have been corrected on DVD/VHS, because Bobby is about to leave because he is sick of Grace playing games. He picks his bag up from the side, then is about to leave, then he suddenly drops his bag by the door, and runs over to Grace and kisses her. Jake then enters, and Bobby is hit. He then walks out of the room, and it cuts to Jake hugging Grace. It then cuts back to Bobby slinging the bag over his shoulder and leaving, so he doesn't leave without the bag.
Correction: Perfectly possible to have sex with underwear on.
