Factual error: When Mike is describing his attempted invasion of Paris to the TA officers, he mentions going on Space Mountain at Disneyland Paris. However, Mike says that it happened in 1994, which must be correct, as the officers in an important interview like this would pick him up on the inaccuracy. Space Mountain did not open until 1995.
Continuity mistake: When Tim and Mike are paintballing, they meet a man who says he is a businessman. As the businessman stands up, he gets shot by Duane Benzie with a yellow paintball. Watch closely as the businessman's jacket is blown open by the paintball impact, and then manages to become buttoned up again.
Trivia: When Daisy bangs on the window in Marsha's room and shouts for Colin, he looks round. However, he looks directly behind him rather than up where Daisy is, at the second floor window. This incident led to Nick Frost theorising that dogs can't look up, which inspired the running gag in the film 'Shaun Of The Dead', a movie created by Spaced director Edgar Wright and star Simon Pegg, starring Pegg and Nick Frost.
