A novelist (Jeff Daniels) facing writer's block and troubled marital relations seeks advice from Captain Excellent (Ryan Reynolds), a superheroic best buddy that springs out of his imagination to become as real as hallucinations can get. The writer's dilemmas only get thornier when he hires a spirited, if off-center, teen girl (Emma Stone) as his new babysitter...even though he doesn't have a baby. Quirky dramedy co-stars Lisa Kudrow, Kieran Culkin. 110 min. Widescreen; Soundtrack: English.
