How we stay independent. Editorial scores are not for sale. TVI may take on paid advisory or research work, but no commercial relationship buys coverage, advance access to scores, favorable treatment, or a change to a published finding.

The TVI Take

Hitchcock's 1954 Frederick Knott stage adaptation, originally released in 3-D. Ray Milland's Tony Wendice planning his wife's murder is the kind of single-location chamber-piece structure Hitchcock excelled at; Grace Kelly's Margot does the harder work as the wife who has to render terror at register the genre rarely affords its female leads.

The scissors sequence is a master-class in editing-as-tension-engine.
