Paul Kaye is not a fan of dance music, and whenever a scene has him in headphones, he is actually listening to punk rock like Sex Pistols or The Clash.
When shooting the scene in which Frankie arrives at Club Amnesia, the crew had originally intended to use a different vehicle. As the day went on and it became apparent that the original car was not going to show, the crew asked a passing motorist if they could use his car. He agreed and was featured in the film as the driver of his own BMW.
The title is Cockney rhyming slang for "it has all gone wrong".
During the montage of Frankie learning to read lips, REGDAB EKOC (COKE BADGER backwards) is written on the chalk board in the class room.
When Frankie is having the extensive hearing tests, the instrument that the doctor uses has markings that go up to 11. This is a reference to Nigel Tufnel's Amp in This Is Spinal Tap (1984).
