The posters and movie titles that appear in the cinemas and streets of London are from movies released between 1999 and 2000 (e.g. The World is Not Enough, Runaway Bride, Mickey Blue Eyes, Stuart Little, etc.), yet this game was released in late 2002. This is because the game was originally going to be released in mid-2000 as one of the launch titles for PlayStation 2, but it was delayed due to some fixes in the map of London. The titles and posters, however, were not updated.
