Troubled Waters is a 1936 British mystery film directed by Albert Parker and starring James Mason, Virginia Cherrill, Alastair Sim, Raymond Lovell and Sam Wilkinson. It was written by Gerald Fairlie from a story by W. P. Lipscomb and Reginald Pound. The film was made at Wembley Studios as a quota quickie by the British subsidiary of Fox Film.
A government agent exposes smugglers in a British town with a dwindling spring mineral water business.
Kine Weekly wrote: "Crime detection and humour are adequately blended in a mystery staged against the background of a remote English village. The plot is rather far-fetched, and the love interest based on the customary quarrel between the pratagonists, apt to be forced."
The Daily Film Renter wrote: "Far-fetched melodrama ... Direction never gets at grips with fantastic subject matter, and action is occasionally difficult to follow. Best performance comes from Alastair Sim as unctuous publican, with James Mason a likeable lead as Government agent. Moderate entertainment for the masses."
TV Guide gave the film two out of four stars, and wrote, "The action is sustained throughout and Mason, as usual, is very good."
