Love at Sea is a 1936 British comedy film directed by Adrian Brunel and starring Rosalyn Boulter, Carl Harbord and Aubrey Mallalieu.

 The film was Brunel's feature-length directorial debut and has been described as "one of the stranger films to emerge from Britain in the 1920s".
 The film's theme of loss of sexual desire, and by implication impotence, was exceptionally frank for its time; oddly however, it appears to have been passed for release without interference by the British film censors, who at this period has a reputation for extreme zealousness where sexual matters in film were concerned.

Adrian Brunel (4 September 1892 – 18 February 1958) was an English film director and screenwriter.
 Brunel's directorial career started in the silent era, and reached its peak in the latter half of the 1920s.
 His surviving work from the 1920s, both full-length feature films and shorts, is highly regarded by silent film historians for its distinctive innovation, sophistication and wit.
 With the arrival of talkies, Brunel's career ground to a halt and he was absent from the screen for several years before returning in the mid-1930s with a flurry of quota quickie productions, a majority of which are now classed as lost.
 Brunel's last credit as director was in a 1940 wartime propaganda short film, although he worked for a few years more as a "fixer-up" for films directed or produced by friends in the industry.
