How to Kill Your Neighbor's Dog.

The story of Peter McGowan, a chain-smoking, impotent, insomniac playwright who lives in Los Angeles. Once very successful, he is now in the tenth year of a decade-long string of production failures. He finds himself bonding with a new neighbor's lonely young daughter who has mild cerebral palsy; and during one of his middle-of-the-night strolls, he encounters his oddball doppelgänger.
