While filming a night scene in Piccadilly Circus, director
Michael Winner set off an unannounced smoke bomb, causing horrendous traffic jams, after which he sped off in a taxi with the film magazine, leaving other members of the crew to be arrested. This incident caused such resentment that for many years afterwards permission to film there was denied;
John Landis'
An American Werewolf in London (1981) was the first to be allowed to do so.
