Hitchcock's creative genius expressed itself through a series of visual or aural effects - startling conjuring tricks calculated to make audiences gasp or giggle. In the course of his long career - he was born in 1899 and started working in films in 1919 - Hitchcock created hundreds of these moments of virtuosity. He employed trick photography, bizarre settings, striking film and soundtrack editing, and telling single shots or whole sequences that had a fantastic or nightmarish reality of their own.
Some of these devices were present in his earliest films, but their full impact was first visible in The Lodger (1926). This silent film was built largely upon a succession of effects. A quick, impressionistic montage at the beginning showed London terrorized by an unknown Jack the Ripper-like murderer. The opening was followed by a series of 'virtuoso' set-piece scenes which made audiences, at that time not usually aware of the director's hand, realize that here was someone of importance behind the camera.
The Lodger's most famous device showed the anxiety of an ordinary suburban family disturbed by the endless pacing of their mysterious lodger upstairs. Hitchcock built a glass floor and filmed from below as the man paced across it - an effect that greatly impressed critics and public in 1926.
His next substantial success, Blackmail (1929), was begun as a silent movie, but by this time cinema audiences were eager to see talking films. The producers decided to insert a few lines of dialogue into the last reel. This did not satisfy Hitchcock who secretly shot additional scenes for the film in sound. His gamble paid off: the producers were so encouraged that they allowed Blackmail to be reshot with sound. It was Britain's first all-talking film.
Despite the addition of sound and dialogue, Hitchcock retained the silent film's freedom of movement. It had a show-piece scene which attracted particular attention. The heroine has, half-accidentally, stabbed a would-be seducer to death. At breakfast the next morning a neighbour chatters about the murder: 'What a terrible way to kill a man. With a Knife in his back. A knife is a terrible thing...' The words run together so as to be almost indistinguishable, except for the word 'knife' stabbing out of its context again and again, as though audibly striking the guilt-ridden girl.
In 1934, he began the great series of six suspense thrillers, made in four years, which carried his reputation round the world and finally took him to Hollywood in 1939. The first of them, The Man Who Knew Too Much, established his penchant for the brilliantly conceived effect as the basis of film-making.
Not everyone approved - Graham Greene, then influential film critic of the Spectator, wrote of The Secret Agent (1936):
It was curious that Greene should have been quite so unsympathetic to what Hitchcock was doing in these films. Hitchcock was always first and foremost a popular entertainer, with no overt pretensions, leaving others to find deeper meanings in his work. His way of involving his audience was to deploy his unique technical skills and extraordinary inventive faculties in the elaboration of telling incident through specific effect.
There is, for instance, the famous shot near the end of Young and Innocent (1937) in which the camera travels slowly across a crowded ballroom during a thé dansant, moving closer and closer to the black-face band, then concentrating on the drummer and finally pausing in an arresting close-up of his eyes twitching - the crucial identifying mark of the murderer.
Memorable though such isolated moments are, the dramatic effects in his films were usually more far-reaching. There were whole sequences that used or exploited well-known conventions of suspense. In The Thirty-Nine Steps (1935), the hero, Hannay, hotly pursued by foreign agents, stumbled into a political meeting. Realizing that his only hope of escape was to get up and speak, he delivered an absurd, off-the-cuff speech and made himself so conspicuous that the villains were unable to do anything to him for fear of giving themselves away.
Hitchcock liked this idea so well that he later used variations of it in two American films which had similar chase formulas to The Thirty-Nine Steps: Saboteur (1942) and North by Northwest (1959).
Yet crowds and public places were not always havens from danger - they could also conceal it. The climactic scene of The Man Who Knew Too Much occurred at the Royal Albert Hall during the performance of a cantata: the sound of the assassin's bullet was planned to coincide with the clash of cymbals at the end of the piece.
Alfred Hitchcock's influence on cinema cannot be overstated. His mastery of suspense, innovative camera techniques, and psychological depth transformed the thriller genre and inspired generations of filmmakers. From Vertigo's exploration of obsession to Psycho's shocking narrative twists, Hitchcock's work remains as powerful and relevant today as when it was first created.
