Blackmailed is a 1951 British noir thriller film directed by Marc Allégret and starring Mai Zetterling, Dirk Bogarde, Fay Compton and Robert Flemyng.

[4] When blackmailerr Mr Sine is murdered by Mrs Christopher, several people who witnessed the crime agree to keep quiet.

The film was shot at Pinewood Studios outside London, with the working title Mrs Christopeher.

Little care has been taken with the sets, obviously stagey, and the direction is slipshod, essaying the odd trick shot, such as the falling of the body from the roof, in a somewhat crude attempt to brighten the surface.

"[6] Picturegoer wrote: "It's a slow and jumbled production in which the main idea – a woman who has committed a murder can't decide whether or not to give herself up because she might involve others – is submerged in a number of trite situations, with unconvincing dialogue and loose direction.
