Did You Know?


With The Jazz Singer (1927) doing spectacular business, the producers decided that the last reel of this predominantly silent film should have sound. Alfred Hitchcock thought that this was an absurd idea and so he secretly filmed the whole thing with sound. See more »

Creative, Subtle, & Suspenseful
1 June 2001 | by (Ohio) – See all my reviews

While remembered as the first sound picture made by Alfred Hitchcock (or anyone else in Britain), there is much more to "Blackmail" than merely historical interest. It reveals the director's subtle creativity, with a carefully structured story that also produces some real suspense, with one of Hitchcock's best cameos and an entertaining chase sequence as bonuses. The movie has a unique feel, as Hitchcock was still using many silent film techniques at the same time that he was experimenting with sound. Not all of this works perfectly, but it does not detract from the film's many positive features.

Alice White (Anny Ondra, voice dubbed by Joan Barry) goes out for the evening with her boyfriend, who is a police detective (John Longden). When they have a series of minor quarrels, Alice decides to go her own way, and meets an artist friend. The artist's intentions are obvious, but Alice is innocently unaware. When he brings her to his studio, there is soon an unpleasant confrontation that sets in motion a turbulent series of events.

The story is carefully constructed not just to produce suspense but also to raise interesting questions in the viewer's mind. Alice feels a terrible sense of guilt and fear over what has happened - communicated to the viewer in a variety of creative ways - but of what is she really guilty? The behavior of the detective boyfriend is partly well-intentioned, but he certainly is not faultless. The moral ambiguity is often subtle, because it takes a back seat to the suspense, and it takes a couple of viewings to appreciate all that is going on.

There is a particularly nice symmetry to the beginning and ending, pointing to the greater significance of the action in between. The opening sequence (filmed in silent movie style) shows the detective and his partner dealing with a suspect in a routine way, not caring about him as a person. In the final scenes, when the detective must help Alice make a final report on everything that has happened, he sees his job in a far different perspective.

"Blackmail" is of the darker type of Hitchcock, like "Notorious" or "Vertigo". While clearly made in a different era, it has the same kind of depth and craftsmanship that distinguished those later, more well-known masterpieces.
