In 1999 the
British Film Institute surveyed 1,000 people from the world of British film and television to produce the BFI 100 list of the greatest
British films of the 20th century. Voters were asked to choose up to 100 films that were 'culturally British'. Some of the selected films were wholly or partly produced by non-UK companies, or made with input from film makers born overseas, but were regarded by voters as having significant British involvement.
