Deliberate mistake: In the scene where Peter Andre and his producer watch the footage of the royal family, in the background you can see princess Diana and the queen mother who had both unfortunately passed away before Little Britain was made. They had to use the old footage but it is still a mistake.
Deliberate mistake: Andy is watching TV, when Bruce (presenter of Bruce's price is right) is calling out for contestants he shouts out three names (Helen Hunt, Akshai Vikoria and Andy Pipkin). However, when we see the contestants - there are four and Bruce says "You are the first four contestants on the price is right" even though only three people were called out. (00:06:55)
