If there's one movie Danny Kaye fans fondly remember, it's the Secret Life of Walter Mitty. The versatile comedian-also an unsurpassed song-and-dance man-plays a henpecked, thriller-genre book writer suddenly enmeshed in a real adventure involving the (literal) girl of his dreams (Virginia Mayo). Kaye benefits from a wonderful supporting cast: Mayo; Boris Karloff as maniacal Dr. Hugo Hollings head; Faye Bainter as Walter's repressive but lively mother; Ann Rutherford as his suspicious fiancée Gertrude; and Gordon Jones as Tubby, who not only has designs on Gertrude, but provides the villain in Walter's fantasies.
