Alfred Hitchcock joins UNESCO register

Alfred Hitchcock's nine surviving silent films will join artefacts such as the Domesday Book in representing the cultural heritage of the UK.

Hitchcock's films - the British director's earliest works - premiered at the British Film Institute last summer following extensive restoration.

They have now been added to the Unesco UK Memory of the World Register.

The register "reflects the richness of UK culture and history, from medieval manuscripts to ground-breaking cinema"....
