Plot hole: When Juliet and David spend some money, they are seen watching a tape of the footage they filmed with a new camcorder. When Alex is in the bath, we see him with the camcorder (it is not a reflection in the mirror) - where did the second one come from?
Visible crew/equipment: Alex and Juliet are cavorting around filming themselves with their new camcorder. In the shot of Alex wearing a black plastic hat and shades you get a quick glimpse of a third person standing very still in the background also filming with a camcorder. It appears to be a tallish fair-haired man wearing a long-sleeved white shirt. Alex and Juliet are supposedly the only two people present, with Juliet holding their camera, so presumably it's a cameraman taking some extra footage from a different angle.
Alex Law: God, you two are sensitive! All I'm doing is implying some kind of ugly sordid sexual liaison. I'd be proud of that sort of thing.
Master of Ceremonies: Ladies and gentlemen, may I have your attention please. First of all may I thank you all for coming along tonight and supporting our appeal to raise funds for the sick children's unit.
Alex Law: You didn't tell me that this was for children. I hate children. I'd raise money to have the little fuckers put down. I want me money back.
Question: Is removing hands, feet and teeth really sufficient to prevent the corpses being identified? What about DNA?
