South Sea Sinner is a 1950 American adventure film directed by H. Bruce Humberstone and starring Macdonald Carey and Shelley Winters.

[1] A cafe owner on a South Sea island plays a dangerous game of blackmail with a fugitive from justice.

[3] Winters admitted to being "nervous and tired" after making three films in five months and was "unused" to Humbersome's "close direction during song and dance scenes.

"[4] She said she had to perform "a suggestive dance" when some exhibitors and their families visit the set and she was upset when an eight-year-old boy filmed her; she asked that he be removed to where she couldn't see him.

[5] The New York Times called it a "ridiculously romance-soggy film which has about as much South Seas flavour as a roadside papaya bar.
