Mordecai Lawner (June 9, 1928 – November 27, 2014) was an American film and theater actor. His film credits included Woody Allen's Annie Hall in 1977, Raw Deal in 1986, Ghostbusters II in 1989, and A Fish in the Bathtub in 1999.
Lawner, a resident of Manhattan for the majority of his life, graduated from City College of New York. A veteran of the U.S. Army, he was stationed in West Germany during the Korean War. In addition to his acting career, Lawner also taught theater at Carnegie Mellon University in Pittsburgh, Pennsylvania, as well as the High School of Performing Arts and the Neighborhood Playhouse School of the Theatre in New York City.
In film, Lawner was possibly best known for playing the father of Alvy Singer, played by Woody Allen, in Annie Hall in 1977. Lawner can be seen in a flashback to Aly's childhood, when the family lived under the Coney Island Cyclone roller coaster. In the flashback, Lawner yells at his wife (Joan Neuman) for firing their cleaning lady, telling her "She has no money! She's got a right to steal from us! After all, who is she gonna steal from if not us?" He also appeared in television, including an episode of Law & Order.
