The infamous Benedict Arnold affair is the basis of the lively MGM costumer The Scarlet Coat. Arnold is played with suitably subtle menace by Robert Douglas, while his principal co-conspirator, Major John Andre, is essayed by Michael Wilding. The largely speculative storyline concerns the efforts of one Major John Boulton (Cornel Wilde), a colonial counterspy, to foil Arnold's plans. Thanks to some deft scriptwriting, the much-abused Major Andre emerges as the most sympathetic character in the film, if only because he is willing to face the consequences for his actions. Less sympathetic is George Sanders in another of his patented "cad" roles, while Anne Francis is the spunky (if unnecessary) heroine.
