The Green Scarf may be set in France, but its cast, crew, and overall tone is impeccably British. Michael Redgrave, hidden beneath a mattress of whiskers, portrays a French lawyer who takes on a seemingly hopeless case. His client, Kieron Moore, is a blind deaf-mute seaman accused of murder. Moore has already confessed to the crime, but Redgrave is sworn to give the best defense possible. At times, however, it is the dullest defense possible, despite a few random spurts of imagination. The Green Scarf was adapted from the novel The Brute by Guy des Cars.
