Continuity: In the final scene before Phil Daniels rides the scooter off the cliff you can see a shadow of the helicopter filming the scene.

Continuity: During the scene where Spider returns to the club and the Mods are off hunting, John Altman is seen leaving the club and riding on the back of a scooter. Second shot, he's dancing.

Continuity: During the end scooter sequence along the cliff tops, you can clearly make out wheel tracks stretching out ahead of Phil Daniels' bike, yet he hasn't been over that ground yet - these are presumably left-overs from a previous take?

Continuity: Leslie Ash's dark shoes change to white trainers halfway through the Riot Scene.

Continuity: In the end of the film when Phil Daniels is about to run over a cliff with his scooter, in the first shot there is a windshield on the scooter. In the second the windshield is gone. In the third the windshield is back again.

Continuity: Routemaster buses have the late 1970s white London Transport logo, not the gold lettering they should have for the mid 1960s when the film is set.

Continuity: The bikes are all wrong.  Rockers at that time went in for the 'Cafe Racer' style with clip-on handle bars, rear set footrests, bum stops etc. The bikes in the shots en route to Brighton had high bars; five years too early.

Continuity: There is a view from Phil Daniels window where a High Speed Train (first operated in about 1975) goes past - the film is set in mid 1960s.

Continuity: The police in the riot scenes have got hair hanging well over their collars - they are supposed to be POLICE in the mid 1960s whereas in fact they are a mob of scruffy layabout 1970s extras.

Factual error: In the scene where Jimmy has just picked Steph up from her place of work. They are cruising along talking, if you look at the twist grip gear change on his scooter, it is in the first gear position for the entire time.

Factual error: Too many post 1964 cars in this film to list.

Continuity: In the party scene, the Who's Quick One/Sell out album is in a different position the second time it's shown.

Factual error: When Jimmy gives Steph a lift home from work on the back of his scooter, they pass a Mk3 Ford Cortina. These were not produced until the mid-seventies.

Factual error: The police vans used in the riot scene are Austin-Morris J4 models, with B registrations, dating them to 1964. The Austin-Morris badge on the front of these vans was only fitted to vans made between 1971-1975. If it is a 1964 van the badge on the front should read Morris Commercial.

Continuity: Jimmy is seen at Waterloo Station catching a train to Brighton. Trains to Brighton have only ever left from Victoria Station.

Factual error: Time travel abounds! As the Air Cadets are seen parading along the seafront they pass a cinema which is showing the mid 70's movie "Heaven Can Wait".

Continuity: In the Brighton street scenes the parading air cadets are wearing service issue pullovers. These were not introduced as part of the uniform until the mid seventies. During the sixties air cadets would have been wearing battledress tunics.

Factual error: During the party scene, as Jimmy changes the record that's playing to My Generation, a copy of The Who Sell Out can be seen in the background. This LP wasn't released until 2 years after Quadrophenia was set, in 1967. The actual version shown is an early 1970s re-issue, so it's actually around 10 years too early.

Factual error: When Leslie Ash is at the checkout she has to check a Cadbury's drinking chocolate tin but it is the wrong aged tin - a 1970's one not 1960's.

Factual error: This error occurs throughout the film, but is most noticeable in the sequence where the mods have arrived at Brighton, and Jimmy & Steph are walking along with the scooters parked behind them. One can see Lambretta models that are yet to be produced. There is an abundance of SX and GP models. SX's were not produced until 1966 and GP's were not seen until 1969. Look carefully and one can see an Indian produced GP that didn't reach the UK until 1970.
