Those who know Jane Fonda only from films such as Julia or Klute will be surprised by her performance in her debut film, Tall Story. Playing a woman attending college for no purpose other than to get her MRS degree, she is the antithesis of the independent liberated woman with which she is commonly identified. It's a love of a performance, and it goes a long way to making this Doris Day-ish piece of romantic comedy fluff enjoyable. Anthony Perkins also helps matters tremendously with a charming performance that emphasizes his endearing, boyish qualities and allows him to have quite a bit of fun along the way. Unfortunately, all their youthful talent and eagerness can't disguise the fact that Tall Story has a terribly weak screenplay, filled with stock characters and situations and a plot that feels cribbed from numerous sources. Joshua Logan's stolid and formuliac direction does not appreciably help matters, but the stars -- and the solid supporting cast -- do manage to make this a moderately enjoyable trifle.
