* They Don't Make'em Like That Anymore Note: Sight & Sound is the official magazine of the British Film Institute, and every 10 years since 1952 it has compiled a list of the all-time greatest movies by polling an international group of critics.

Welles was the only director represented by two films in the top 10. "The Magnificent Ambersons" placed eighth in the poll . . . The other films were: Akira Kurosawa's "Seven Samurai," Stanley Donen and Gene Kelly's "Singin' in the Rain," Federico Fellini's "8 1/2," Sergei Eisenstein's "Battleship Potemkin," Michelangelo Antonioni's "L'Avventura," Alfred Hitchcock's "Vertigo," Buster Keaton's "The General" and John Ford's "The Searchers," the last two tying for last place. . .
