Anachronisms: Although set in 1966, most of the pop songs in the soundtrack were released after this time. Some of the songs featured were hits in 1969.
Anachronisms: One of the cars in a London street scene has a 1967 registration although the film is set in 1966.
Continuity: Carl's hair completely changes position (between shots) when he's talking to Quentin in his cabin at the dining table.
Anachronisms: Although set in 1966, dome-shaped CCTV cameras are visible on both sides of the National Gallery in the scene on the building's steps.
Continuity: When The Count threatens to say the f-word live on air, in some shots his hand is holding the microphone, in others his hand is by his side.
Errors made by characters (possibly deliberate errors by the filmmakers): The Government minister in charge of closing down the pirate radio stations is depicted as a right-wing reactionary, with a grand home with servants. In fact the responsible minister was Tony Benn, then the Labour government Postmaster General at the time, who is known as one of the most left-wing and socialist senior politicians ever.
Anachronisms: Gavin is wearing MYKITA Sunglasses which use a patented hinge system which was invented recently.
Continuity: In the Christmas scene at the government minister's house, the minister's daughter offers Twatt a mince pie. A mince pie can be clearly seen already on his plate and when he accepts the (apparently second) the other has vanished.
Continuity: In the final scene when they are on the bow of the ship, just before it sinks, where are the ship's mechanical crew; captain, engine operators etc, which can be clearly seen in the previous scene.
Crew or equipment visible: When there is an ariel shot, the helicopter is visible in the sea.
Crew or equipment visible: When Rhys Darby's character has been thrown off the boat to 'swim', there is the shadow of a camera on the backs of the crew members who threw him off.
Continuity: When Quentin salutes his crew, The Count salutes him, and in the next shot The Count is raising his hand to salute.
Anachronisms: When Rhys Darby's character Angus is first introduced, He has a modern pair of "Panasonic" headphones on.
Revealing mistakes: The ship is sinking at about 45 degrees, yet the DJ is able to play a record on a level turntable.
Continuity: When they start the final record by Procol Harum, we watch a single at 33rpm. That is possible as it was a very long track. Nevertheless when we have a second view of the turntable a few shots layer, it obviously plays at 45rpm.
Errors in geography: The Boat is sinking at a position given as 53 degrees 17 minutes North and 2 degrees 15 minutes East - which is a position 70 km Northeast of Bacton in Norfolk, (the nearest town on land) - however Gavin is requesting anybody with a boat in Suffolk to help with the rescue. Suffolk is a long way to the South and he would do better to ask for help from anyone in Norfolk.
