This is one of my all time favorite movies. It's sophisticated, funny, and a real murder mystery. Woody Allen and Diane Keaton are married and live in an apartment building in Manhattan. Allen is a book editor who is working on a book with Anjelica Houston. Allen's best friend is Alan Alda who is also a writer. Keaton is a great cook who is thinking of opening a restaurant. Allen and Keaton become friends with an older couple down the hall from them. The husband is restoring a famous movie theatre in downtown New York. Anyway, the wife drops dead. Alan and Houston hook up. The rest of the movie the four of them try to solve the murder. It's really great.
