Revealing: In the hut in the swamps Zack lights a candle. The resulting light is obviously from a spotlight because the flame and the shadows are perfectly still.

Continuity: When Jack and his girlfriend talk in his room she is lying on the bed, her head rested against a metal frame. In a different angle, seen from behind, the frame is gone and her head is on the pillow. Later it's on the frame again.

Continuity: While Jack, Zack, and Bob paddle through the swamps they change places. This is hardly possible considering the shape and the shakiness of the boat and Bob's lack of swimming skills, plus there is no reason to take such a risk.

Plot hole: Where did Bob find a knife to skin and clean the rabbit? And why did he leave the ears and front paws?

Continuity: During their escape the three protagonists have to wade through a canal. A few moments later their clothes are dry again.

Continuity: When Zack and Jack walk from the place where the boat sank their shirts are perfectly OK. During the next rest they start fighting, and you can see that both their shirts are torn badly before the fight even begins.

Continuity: When Jack and Zack look through the window into Luigi's Tin Top there is an empty table between the dinner table and the window. In the following shot inside the house the empty table and chairs are in a different place, closer to the wall. In the next morning they are in the original position again.

Continuity: At the end of the film Zack and Jack hide in some bushes while they are watching Luigi's Tin Top. The are shown from the front and from the back, and in both shots the bushes are different.

Continuity: When Laurette and Zack have a fight she throws his records around. First some whole records are lying on the floor, later they are broken and at different spots. Also some records on the bed disappear or change their places.

Factual error: When Jack meets the prostitute at the corner there is a car parked the wrong way in a one-way street.

Audio problem: When Laurette throws Zack's stuff out of the window it sounds as if they live on the ground floor. When Zack has left the apartment you see that it is on the second floor.

Revealing: When the three friends have a rest during their escape through the swamps you see water in the background where the ripples and the reflections are totally still, in contrast to all other shots before and after. It must be a painted backdrop.

Continuity: On the run through the swamps Zack and Jack leave Bob behind because he can't swim. When Zack comes back a minute later to help Bob through the water he doesn't come from where he went before.

Continuity: When the three protagonists come to the hut in the swamps, Bob's shirt is first tucked in in the back and hanging loose in front. When they step up the porch it is tucked in in front and loose in the back. Finally, when they enter the house, it's again tucked in in the back and loose in the front.

Plot hole: Shortly before the boat leaks and sinks only Bob notices the water coming in when he puts his feet down. The other two, who had their feet down all along, don't.
