During the film it shows that English F.A. is based at Lancaster Gate, they moved away to Soho Square several months ago during the filming, and Wembley Stadium has been shut down for almost 7 month's upon the release of the film.
There were only a maximum of 300 extras used at Wembley Stadium. The Moving Picture Company were responsible for all the visual effects, which included crowd replacement/replication at Wembly and the Maracana. Thanks for the compliment.
During the second secret interview with the dissident players, one of them claims that some players are "checking to see if they have Irish grandparents, to jump ship". However, FIFA rules do not allow a player to change national team once he has played an international game.
Two (fourth-tier) Third Division players named Benson & Hedges are picked by Bassett by accident because he writes the team down on the back of a packet of cigarettes. One is aged 46 and both are portrayed as comically old, unfit and so on. While fourth-tier players would not be up to the standard required for international football, their unsuitability is grossly exaggerated.
