Cyrus

Jamie (Catherine Keener) informs her ex-husband John (John C. Reilly) that she is getting married. Even though they have been apart for seven years, the news devastates John, who was already depressed. At a party the next night, John gets more and more drunk until he ends up urinating in the bushes, where Molly (Marisa Tomei) strikes up a conversation. Molly goes back to John's house but leaves during the night, after they have had sex. Molly returns for dinner the next night, and again leaves after they have had sex. John follows her to her house and falls asleep in his car. The next morning, he approaches the house and meets Molly's 21-year-old son Cyrus (Jonah Hill). Cyrus invites John inside and makes friendly conversation with him. Molly is startled to see John in her house when she returns, but the trio have dinner together. John is unnerved by the unnatural intimacy between Molly and Cyrus.
