Brief Ecstasy (also known as Dangerous Secrets) is a 1937 British drama film directed by Edmond T. Gréville and starring Paul Lukas, Hugh Williams, Linden Travers and Marie Ney.

[1][2] It was made at Ealing Studios.

Writing for Night and Day in 1937, Graham Greene gave the film a good review, expressing admiration for producer Perceval's ability to "wring twenty shillings' worth out of every pound" and director Gréville's recognition that for a film whose subject is sexual passion "the story doesn't matter; it's the atmosphere which counts".

Greene praised Gréville's "wanton and vivid" depictions of "undifferentiated desire" as well as his French education in "photograph[ing] a woman's body - uncompromisingly", and noted that "the film at its finest [...] generalizes", and "there isn't, thank God, any love in it".
