"Joy," too, looked surprisingly unjoyful. In it, Jennifer Lawrence reteams with her "Silver Linings Playbook" and "American Hustle" director Russell to play Joy Mangano, a single mother who invented the Miracle Mop. Fox didn't give much of the movie away on Thursday -- just a seconds-long montage with snippets from the film set to church bells. Lawrence was often stone-faced, or looking sad -- at the mop factory, on set at the Home Shopping Network, at a funeral, behind bars, in a snowstorm. This housewife doesn't have time for exploding science ovens, folks.
