A Vicary Street sign can be seen though the telephone box when Jo rings the police. Vicary Street was in Blenheim Gardens running off Brandon Road but no longer exists, having been demolished during the construction of the Blenheim Gardens Estate.

Under-rated suspense masterwork., 16 January 2001
Author: Glenn Andreiev ( from Huntington, NY

When you start watching the 1956 version of THE MAN WHO KNEW TOO MUCH, you'll think it's a minor work by Alfred Hitchcock. The countless scenes showing a lovely, but buffoonish vacationing American couple (James Stewart, Doris Day) seem to lead nowhere. But, hold on, about thirty minutes into the film, during a very dreamlike murder sequence (which takes place in bright sunlight, and involves blue paint) the film really takes off. Personally, I find the opening "character development" sequence between protagonists James Stewart and Doris Day very charming. It sets you up for the second and third acts of the film. You get to like this couple so much, you are raelly rooting for them as they try to rescue their kidnapped son amidst a plot to assassinate a visiting diplomat. Of course, the high-point of the film is the assassination itself, a twelve minute wordless sequence. Hitchcock beautifully brings us back to silent film! The ending, which involves a rescue at an embassy, is wonderfully silly and tense. For those not familiar with Hitchcock, this is Hitchcock's own remake of a film he made under the same title in 1934 in England. This is one of my favorite Hitchcock films. It's proof that this master loved his audience and wanted to keep them thrilled!
