Revealing mistake: After Mike burns the stumps (aka Rik), the special patch that was set on fire on the back of Rik's overalls is visible.
Revealing mistake: When the bus explodes, an explosive charge can be seen on the ground beside the bus just before the explosion. (00:34:01)
Revealing mistake: When the bus falls off the quarry, there appears to be an open door next to the driver's seat, presumably so that the stunt driver can jump out of the bus before the crash. (00:33:45)
Continuity mistake: On the bus, when Vyvyan suggests that they pick up some girls who can do their cooking and cleaning, Neil can be seen in the background looking at Vyvyan. When the shot cuts back to the other three, Neil is looking at Rick. (00:32:55)
Continuity mistake: When Vyvyan crashes into the lamp post, he has his right hand placed on top of the steering wheel. In the next shot, he has his right hand positioned at the top right corner of the steering wheel. (00:30:55)
Other mistake: Whilst Rick is trying to rob the bank, a police officer announces that the police are outside and have the building surrounded. Once the main characters get the money, they run out of the bank, but the police are nowhere to be found and only begin to arrive once they get into the car. (00:29:45 - 00:30:37)
Other mistake: When the bank robber is holding the employee hostage, he has him place the money into a sack on the desk with "Euston Film Property Department" written on it. There is also a second sack with "Swag Bag" written on it that has money inside it. Later, when the robber attempts to leave the bank, he only has the Swag Bag sack, and the Euston Film Property Department sack is never brought up again. (00:29:10 - 00:30:30)
Revealing mistake: When Vyvyan is hitting Rick with the cricket bat, it wobbles when he swings it, revealing it to be a rubber prop. (00:07:15)
Revealing mistake: When Neil imagines himself turning into the Hulk, he throws the other three characters to the ground. When Mike is thrown, just before the shot cuts to him landing on the ground, the ground can be seen bending inwards when Mike's foot touches it, revealing it to be fake. (00:05:13)
Chosen answer: It wasn't referring to anything real, just that the government's bureaucratic naming, The Guardian's mangled spelling or Rick's bad pronounciation resulted in the unlikely word "Footumch" being spoken.
