Trio (also known as W. Somerset Maugham's Trio) is a 1950 British anthology film based on three short stories by W. Somerset Maugham: "The Verger", "Mr. Know-All" and "Sanatorium". Ken Annakin directed "The Verger" and "Mr. Know-All", while Harold French was responsible for "Sanatorium".
Trio is the second of a film trilogy, all consisting of adaptations of Maugham's stories, preceded by the 1948 Quartet and followed by the 1951 Encore.
The film was nominated for the Academy Award for Best Sound, Recording (Cyril Crowhurst) and was the final one released under the Gainsborough Pictures banner.
In The New York Times Bosley Crowther noted, "another delightful screen potpourri, made from short stories of W. Somerset Maugham...Wonderfully rich...Shot through with keen, ironic humor"
