About 35 minutes into Knock Knock, Keanu Reeves enters his bathroom and encounters a wet and topless Ana de Armas. Keanu then turns around and is greeted by a naked Lorenza Izzo. They then have sex but most of the nudity is shot close up and with quick edits. The next day, Ana and Lorenza open their robes and press their breasts against a window in the background while Keanu is on the phone. Knock Knock is currently playing at the Sundance Film Festival.
