Continuity mistake: In the Daffyd sketch, Daffyd has two nipple piercings. As those other gay men come through the door and he pushes them back, his right nipple ring has moved up his body - obviously a clip on. It stays there for a few moments, until the next shot where it's back on his nipple, with no time to put it back on. (00:10:05)
Continuity mistake: In the sketch where Lou is about to paint Andy's bedroom, in the first wide shot, as Lou picks up the red paint, there is a paint tray, with two rollers and two brushes in it. Then when it cuts, the two rollers are now laying on the floor, and aren't in the tray. (00:05:45)
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.
