Katharine Hepburn portrayed everything from queens to a Chinese peasant in her splendid career, but her most unusual role may just be Trigger Hicks in Spitfire. The elegant, cultured Hepburn plays an ornery, rock-chuckin' mountain gal who finds God - and a knack for faith healing - in a pack of stolen Bible cards. But when she exercises her self-declared miraculous powers on a sick baby, the local folks figure Trigger is a force of supernatural evil. Two fine leading men, Robert Young and Ralph Bellamy, lend skilled support in a picture that's Hepburn's all the way: After the story of Spitfire is forgotten, memories of Miss Hepburn's performance will remain (The Times (London).
