Goofs

When Alex and David are fighting on the floor David pins Alex to the floor and grabs a knife from the worktop to stab through Alex's shoulder. The knife on the worktop is regular 14-centimeter kitchen knife which would not go through Alex's shoulder. However the knife through Alex's shoulder and the floorboard later on in the same scene is at least 30 centimeters.

When the trio are driving across North Bridge at night, they have a lengthy conversation before the camera cuts back to the rear of the car, still crossing the bridge. They could have crossed the bridge twice at the speed they are driving.

Despite the numerous holes that David drills into the ceiling from the attic, numerous upward shots in the flat afterwards show no visible holes.

When Alex calls the inspector, just after he finishes dialing he runs his hands though his hair and the cut on his forehead is missing. The scene cuts away and when it returns the cut has reappeared on his face.

On the name plate on the door David's last name is spelled "Stevens" but in the credits it's spelled "Stephens".

Hugo's body has been left in his room for at least a couple of days but it shows no sign of decomposition or rigor mortis when it is disposed of.

When the second intruder enters the loft area to get the money from the water tank he reaches around a wooden support to turn the light switch on. The light switch is not visible to him yet he reaches for it as if he has been to the loft before.

When they are watching the home movie recorded with their new camera there is a shot of Juliet and Alex in the bath, showing the very camcorder the clip is being filmed on.

During one of the shots of Hugo's corpse (after the scene at Alex's workplace), you can clearly see the dead man's jugular pulsating.

In the end credits, The Wicker Man footage is acknowledged erroneously as "The Wickerman."

The film is set in Edinburgh and Alex works on North Bridge, presumably for the Evening News newspaper. However, when the first body is found in the woods Alex arrives home with an armful of the copies of the Evening Times, Glasgow's evening newspaper (the movie was partly shot in Glasgow).

There is no need for them to dispose of Alex's body at all. As there would be no trail for the pile of money, this is the only thing they need to hide (either in one place, or split it between the three of them first) and then launder. They are then free to report Hugo's death to the authorities. As he had just moved in, there is little reason for them to be under suspicion.
