In Robert Bloch’s novel Psycho, Norman Bates was plump, balding, bespectacled and 40 years old, the physical antithesis of the lean, lanky and boyishly good-looking 28-year-old Anthony Perkins. The casting satisfied Hitchcock’s desire to create as much sympathy for Norman Bates as possible. There is nothing about Perkins to suggest a homicidal psychopath. He is a clean-cut young man, who soon reveals himself to be charming, confident, and witty.

Grace Kelly, Eva Marie Saint, Ingrid Bergman, Kim Novak, Tippi Hedren, Janet Leigh – these are only the best-known of that special breed, the Hitchcock blonde. For some reason, whether he wanted a femme fatale or a romantic accomplice or a tragic victim, Hitch liked them blonde, and preferably glacial.

Alfred Hitchcock isn't the only director who appeared in his own movies - François Truffaut, Orson Welles, Martin Scorsese and M Night Shyamalan are among many others who have done the same - but he is by far the one who has done it most frequently. He appeared, to the best of film historians' knowledge, in 39 of his 53 films.

The epithet "mellifluous" might have been invented to describe Herbert Marshall’s voice. It was lucky that sound came along at the time Marshall, after a prestigious stage career, entered films when he was almost 40. We don’t hear those beautiful tones until some time into Murder!

In Vertigo Kim Novak plays two women who are really just one. First Madeleine, a supernatural siren, a woman apparently possessed by her tragedienne great-grandmother Carlotta Valdes. However, it’s a performance within a performance and she’s merely a facsimile, a devastating creation played by an agent in a murderous plot. The imposter manipulates Scottie (James Stewart) into loving her only so that he may witness her apparent death. Then there’s Judy, the real woman behind the performance who is persuaded back into the part when Scottie can’t let go of Madeleine’s ghost.

Hitchcock’s penultimate film was the grubby, squirm-inducing Frenzy, and Barry Foster's depiction of the grim killer Robert Rusk is central to the disquieting aura it casts. The film’s production was problematic enough, having been cut by the BBFC before release. It also had casting problems – Michael Caine turned down the lead role. Hitchcock dismissed composer Henry Mancini from soundtrack duties after having commissioned him. Hitchcock’s first British production for two decades wasn’t an easy ride for the director or audiences.

It’s always a thrill watching The 39 Steps’ Richard Hannay (Robert Donat) doing daredevil feats on the Flying Scotsman as it speeds across the Forth Bridge, kissing a Scottish crofter’s jealously guarded wife, and bringing down the house with an inane extemporized speech at a constituency meeting.

Long before the invention of digital technology and the birth of Keira Knightley, cinema shows in Britain contained not one feature, or two features, but also what the advertisements called a "full supporting programme". That meant newsreels, maybe a cartoon, or what the trade called "interest" films: travelogues and such. Many of those weren’t interesting at all, nor have they become so with age, though that’s not the case with the 12 examples drawn by the BFI National Archive from a travelogue series shot all over London’s highways and byways in 1923/1924. 

The premiere of the newly restored version of Alfred Hitchcock’s 1929 silent classic Blackmail, outdoors at the British Museum, will go down as one of the defining moments of the London 2012 cultural extravaganza. This was a thrilling, beguiling, resonant celebration of the city and its greatest film-maker.

The Storyville documentary strand must rank as one of the special glories of British television. As its opening titles unfold in different languages, we can only celebrate programmes that still give time to international stories, told in their own time, and allowing an eclectic, sometimes oblique view on their subjects. Hitler, Stalin and Mr Jones, a film by George Carey (pictured below), serves as a rallying cry to endorse exactly that.
