Frederick Knott's suspense play of man plotting wife's murder
and subsequent police investigation: stagey at times but slick
and entertaining. Filmed in 3-D. Remade for TV.
The movie was shot
in 3-D although it was never released that way until after Hitchcock's
Hitchcock arranged to have Grace Kelly dressed
in bright colours at the start of the film and made them progressively
darker as time goes on.
Hitchcock makes his cameo appearance 13 minutes into the film, on the
left side of the reunion photograph.
