Nine silent films by Alfred Hitchcock have been added to a UNESCO register.
Hitchcock's earliest films were shown at the British Film Institute last summer following extensive restoration.
They have now been added to UNESCO's UK Memory of the World Register.
The BBC reports the BFI spent three years restoring the nine films, made between 1925 - 1929.
Titles include Hitchcock's debut feature The Pleasure Garden and The Ring, a boxing drama. A 10th film made during the period, The Mountain Eagle (1926), remains lost.
Last year, Hitchcock's Vertigo replaced Orson Welles's Citizen Kane at the top of a poll by the Sight & Sound magazine as the greatest film of all time.
