Shallow Grave goofs

A boom microphone is visible reflected in the car window whilst Alex pushes Hugo's car into the lake.

While the three of them are driving over North Bridge at night, they hold an extended conversation before the camera cuts back to the back of the car, which is still on the bridge. At the speed they're travelling, they could have crossed the bridge twice.

During the scuffle on the floor, David pins Alex down and snatches a knife from the worktop, attempting to drive it through Alex's shoulder. The knife on the worktop is a standard 14-centimetre kitchen knife, which would not be long enough to penetrate Alex's shoulder. However, the knife later seen embedded in Alex's shoulder and projecting through the floorboard in the same scene appears to be at least 30 centimetres long.

On the nameplate on the door David's surname is spelt "Stevens", but in the credits it is spelt "Stephens".

Although David bores several holes in the ceiling from the loft, subsequent low-angle shots within the flat show no visible holes.

Although several scenes are meant to occur at night, whenever the staircase is shown sunlight is streaming in through the windows.

As Alex phones the inspector, immediately after he has finished dialling he runs his hands through his hair and the gash on his forehead is gone. The scene then cuts away, and when it returns the wound has reappeared on his face.

When Juliet examines Hugo's corpse, she shuts his eyes. Later, as they bury him and David prepares to smash Hugo's teeth, his eyes are wide open.

While Juliet, David and Alex are removing the body from their flat, Juliet dons a pair of latex gloves. In the very next shot, when she pushes the body off the bed, her hands are bare.

During Alex and David's struggle on the floor towards the end, one shot shows the fridge door shutting, yet in the following shot it is wide open.

Whilst David is talking to his boss, the file — moments before the boss hands it to David — moves from lying on the table to being in the boss's hands between shots.

The film is set in Edinburgh and Alex works on North Bridge, presumably for the Evening News. However, when the first body is found in the woods, Alex comes home carrying an armful of copies of the Evening Times, Glasgow's evening paper (parts of the film were shot in Glasgow).

Hugo's body lay in his room for at least a couple of days, yet when it was disposed of there were no signs of decay or of rigour mortis.

In the closing credits, footage from The Wicker Man is incorrectly credited as "The Wickerman."

They needn't get rid of Alex's body at all. With no paper trail for the cash, the money is the only thing they must conceal (either in a single location, or divided among the three of them first) and then launder. Once that is done, they are free to report Hugo's death to the authorities. As he had only just moved in, there would be little basis for suspicion falling on them.

When they watch the home video recorded on their new camera, a shot of Juliet and Alex in the bath plainly reveals the very camcorder used to capture the footage.

When the second intruder climbs into the loft to retrieve the cash from the water tank, he feels around a timber support to turn the light on. The switch is out of his sight, yet he fumbles for it as though he has been in the loft before.

In one particular shot of Hugo's body (following the scene at Alex's place of work), the deceased man's jugular vein can be clearly seen throbbing.

The corpse of the first intruder, hurled from the loft, is clearly a prop.
