Revealing: At the beginning when Frank is directing the vans, we see that one gets its windscreen broken by a ladder from another van. However, the glass breaks just before the ladder touches it.

Continuity: When Frank is on the phone taking down the details off his boiler repair job, he is told the address is 26 Upton Down, but the house where Frank does the job is number 24.

Visible crew/equipment: Towards the end, just before he gets into his car, a boom mike shadow can be seen on Mr Lewis's jumper.

Revealing: When the second piece of scenery falls on Frank, it has a tear halfway down and a hole in it that Frank's head goes through. A few seconds earlier, these weren't there. Maybe they were put there to make sure Frank's head went through, or else this is the second take.

Other: When Frank open his front door to Mr. Jackson the walls around wobble.

Deliberate "mistake": Just before father O'Hara explains to Frank why he isn't in the nativity play he says to Betty "Perhaps I will have that cup of tea after all Mrs. Spencer" Betty goes to the kitchen but father O'Hara never gets his cup of tea.

Visible crew/equipment: When Frank is loading the lorry at the warehouse, he drives the forklift onto the lorry, then the lorry drives off while he and the forklift truck are still on the back. As the lorry pulls away you can see the camera crew on the other side of the road filming the next shot.

Continuity: When the mini goes into the horse box, Frank is on the roof. When it stops, Frank is thrown onto the horse's back. But when the car first goes into the horse box, there is no horse inside it. Also, you can see the ramps put on the tailboard so the car can drive up it. They fall away as the horse box drives off.

Other: The walls of Frank's house wobble whenever he opens the front door.

Revealing: When the bottle of wine explodes in the cupboard, just after Frank has shaken it, you can see a pushrod inside the cupoboard pushing the top up.

Continuity: Just before Frank's car crashes into the sea, the shots from inside and outside the car do not match. )utside shots show Frank driving in a built up area while inside shots show countryside .

Revealing: Just before the runaway mini goes into the horsebox you can see the stunt man dressed all in black laying down inside the car steering it.

Continuity: When Frank is taking his driving test in the Hillman Imp, he is driving slowly down a narrow and winding road. He is being followed by the green van, flashing its lights at him, and as the van turns off Frank hears a train hoot, then drives round the barriers at a level crossing. The terrain suddenly changes from a narrow road in the hills, to a wide road on flat land. Then while Frank is driving to the sea, he passes the same parked brown Vauxhall Victor twice.

Continuity: When Frank is driving the white mini in the country lane, trying to overtake the lady on the bike, there is nothing behind the mini, but then a split second later he is being followed by a silver Renault. As he tries to overtake the cyclist, Frank is followed by a brown Triumph, then a second later a yellow Ford Anglia is following him. Frank also appears to drive along the same stretch of road several times, as he keeps passing the same parked cars.

Revealing: While Frank is taking his driving test, he and Mr. Hayes are wearing standard road safety belts in the car. But when the car is in the sea after crashing through the fence, both the occupants are wearing motor racing type safety harness obviously fitted for the stunt.
