On the Buses (1971) - 10 mistakes

Continuity: Vera gets onto her bus just after Stan and Jack have put spiders in the cab. She is wearing boots when she discovers the spiders, causing her to run into the back of the lorry. As she does so, it is evident that she is wearing shoes.

Continuity: The same two cars pass the lorry before and after Vera crashes into it.

Factual error: In the scene where Blakey nearly catches Jack in the turn round Betty's house, Blakey tells them to get moving as they are late. At first they both go through the passenger door of the bus at the back before Stan goes round the front to drive, but the bus drives off too soon for Stan to walk to the front, climb in the cab, start the engine and drive off.

Revealing: When Stan drives through a puddle and splashes Blake the water just reaches Blake's knees but when the shot changes the water that goes in Blake's face is obviously thrown at him from a bucket.

Revealing: When the sidecar separates from Arthur's motorcycle the extra wheel fitted so that it can roll away can be seen it has gone when the sidecar comes to rest.

Continuity: When the bus stops on the motor way the advert on the side is for "whitbread tankard" but when that bus arrives at the depot two hours late the advert is now for "KP nuts" although the buses registration number stayed the same in both scenes (VNO 862).

Continuity: When Stan stops the bus to collect his washing from the laundrette there is a white mini parked outside the laundrette with a brown car parked in front of it. But when Blakey confronts Stan coming out of the laundrette with the bag of washing, the brown car has gone without enough time for it to start up and drive off.

Continuity: In the last scene, when Stan boards his bus inside the depot, the registration number is "WNO476" but, as soon as he drives out the front entrance, it changes to "VNO857".

Plot hole: When Olive gets into the motorcycle sidecar to go to hospital to have her baby her weight lifts the motorbikes rear wheel off the ground. Stan solves the problem by riding on the rear off the pillion to keep the wheel on the ground. Stan never intended to go to the hospital until this problem occurred, but he was already holding a crash helmet in his hand from the start off this scene.

Plot hole: When Olive gets in the motorcycle sidecar to go to hospital to have her baby, her weight lifts the bikes rear wheel off the ground. Stan rides on the rear of the bike seat to keep the wheel on the ground. However, Stan never intended to get on the bike until this problem occurred but he was holding a motorcycle helmet from the start of this scene.
