The film features a joke reference to an ex-drummer of the notoriously "uncool" 1980s rock band Marillion. The band were made aware of this and members were invited to the Leicester Square premiere of the film. The band's original drummer, Mick Pointer, was fired after their first album due to his limited technical abilities and they had a total of five drummers in the space of a year between their first two albums. The film does not make clear which of these drummers the character is supposed to be. The band were quoted: "We know Marillion are seen as 'uncool' but we were delighted to be a part of it."
During the scene where Alan and the hostages are discussing Pat's jingle, (just before Alan says "I'm gonna lay down a rhythm track"), Alan picks up a bass guitar and plays the same song that he plays air-bass to in S2E5 of 'I'm Alan Partridge' [1997-2002]. This song is 'Music for Chameleons' by Gary Numan.
There is a deleted scene where it turns out the entire film never happened, and was just Alan's vision. However, it is not known if this was an original idea for an ending or just a joke.
Lynn drives an old 1985 Austin Metro. In the second episode of I'm Alan Partridge (1997) she unsuccessfully tries to persuade Alan to trade in his Rover 800 for a much smaller and cheaper Rover Metro. Alan scornfully says he will not drive a "MiniMetro", which was the model's original name for the first two years of its production (eventually it was sold as the Rover Metro after the Austin brand became defunct). The model Lynn drives is from after the 'MiniMetro' became just 'Metro' but it's the same design.
