In Alfred Hitchcock's world, theaters are where danger stalks the wings, characters are not what they seem and that "final curtain" can drop any second. The droll Stage Fright springs from that entertaining tradition. Jane Wyman plays drama student Eve Gill, who tries to clear a friend (Richard Todd) being framed for murder by becoming the maid of flamboyant stage star Charlotte Inwood (Marlene Dietrich). Filming in his native England, Hitchcock merrily juggles elements of humor and whodunit and puts a game ensemble (Alastair Sim, Sybil Thorndike, Joyce Grenfell, Kay Walsh and daughter Patricia Hitchcock) through its paces. No one turns a theater into a bastion of dread like Hitchcock, and Stage Fright is proof positive.
