The trailer for “Will Success Spoil Rock Hunter” is a trip. For a flick that’s already more self-conscious than a neurotic teenager, the 1950’s style tell-us-about-the-movie-and-show-clips-too approach makes it a pancake on a pancake on French toast. It’s totally meta and totally reflexive. It makes sense, too, since director Frank Tashlin used to direct episodes of Looney Tunes for Warner Bros. But in the middle of all that, you’ve got Jayne Mansfield looking absolutely smoking hot. And that’s really what keeps you watching if I may say. – Jeff
