Impulse is a 1954 British second feature[1] film noir directed by Cy Endfield (as "Charles de Lautour") and starring Arthur Kennedy, Constance Smith and Joy Shelton.

[2] It was written by Endfield (as "Jonathan Roach") and Lawrence Huntington from an original story by Carl Nystrom and Robert S. Baker.

With his wife Elizabeth on a short break visiting her mother, he gives a lift to sultry nightclub singer Lila when he finds her stranded on the road at night.

The film was shot at Nettlefold Studios, Walton-on-Thames, Surrey, with sets designed by art director Wilfred Arnold.

The story is by no means completely convincing, but is made reasonably credible by a standard of acting somewhat above the average for a production of this type.
