US:Citizen Kane has been voted the greatest film in a poll by the American Film Institute of actors, directors, screenwriters, editors, cinematographers, critics and historians.
The results were announced in a TV programme, 100 Greatest Films of All Time, broadcast nationally on the CBS network in the US on Wednesday night.
When the institute last conducted the poll in 1996, Citizen Kane, which was released in 1941, also topped the list.
The Godfather and Casablanca are placed second and third this time, reversing their positions in the 1996 poll. There were only two additions to the top 10 since the last poll was taken - Martin Scorsese's Raging Bull climbs from 24th to fourth place and Alfred Hitchcock's Vertigo goes from 61st place to ninth.
The new top 10 is completed by Singin' in the Rain (fifth), Gone With the Wind (sixth), Lawrence of Arabia (seventh), Schindler's List (eighth) and The Wizard of Oz (10th).
The two films to lose their places in the top 10 are The Graduate (now 17th) and On the Waterfront (19th). The film making the biggest climb is John Ford's classic western, The Searchers, which rises from 96th to 12th.
Only four films released since the 1996 poll made their way in to the top 100 - The Lord of the Rings: The Fellowship of the Ring (50th), Saving Private Ryan (71st), Titanic (83rd) and The Sixth Sense (89th).
Of the 19 other newcomers to the top 100, the highest placed are The General (18th), Intolerance (released in 1915 and the oldest film on the list, 49th) and Nashville (59th).
New additions also include Cabaret, The Shawshank Redemption, In the Heat of the Night, All the President's Men, A Night at the Opera, Sophie's Choice, The Last Picture Show, 12 Angry Men, Do the Right Thing, Blade Runner, Toy Story and Sunrise.
Among the films that dropped off the top 100 from the 1996 poll are Dr Zhivago, From Here to Eternity, Amadeus, The Third Man, Fantasia, Rebel Without a Cause, Close Encounters of the Third Kind, Dances With Wolves, Fargo, Patton and Frankenstein.
The decade represented most often in the top 100 is the 1970s, which provides 20 entries. The director with the most films on the list is Steven Spielberg with five, while Alfred Hitchcock, Stanley Kubrick and Billy Wilder have four films each.
Robert De Niro and James Stewart are the actors with the most films in the top 100 - five each - and three actresses have three films each: Katharine Hepburn, Diane Keaton and Faye Dunaway.
