The fifth feature of noted Spanish filmmaker Alex de la Iglesia, La Comunidad is a frenetic black comedy set in a decrepit old house in the center of Madrid. One of the house's new residents is Julia Garcia (Carmen Maura, whose performance won her a best actress award at the 2000 San Sebastian Film Festival), a real estate agent who has taken an apartment to revive her sagging marriage. One day, while engaging in some bedroom bliss, Julia and her unemployed husband Ricardo (Jesus Bonilla) are attacked by cockroaches that rain down on them through a crack in the ceiling. During a subsequent investigation of the upstairs apartment, firemen discover a man's rotting corpse. Julia later conducts her own investigation of the apartment and discovers almost 15 million dollars hidden away under the floor boards -- the result of a soccer-pool win by the apartment's dead owner. She decides to take the winnings and run, but while removing the cash, meets her neighbor Ramona (Terele Pavez), who quickly becomes suspicious of Julia's activities. It turns out that everyone in the building knew about the money and agreed to share it amongst themselves, a plan severely compromised by Julia's desire to keep the money for herself. After inviting Julia to a welcome party held by the residents' association, her neighbors go to extreme lengths to get the money, and plenty of cartoon-colored murder and mayhem ensues.
