 Woody Allen decided to make the film for two main reasons. One was  because he had always wanted to do a "chamber piece", a film with a  small cast (there are only six principal characters, and only nine  in the entire film) in a single location. The other was for the  location itself, Mia Farrows Connecticut country house, which  inspired Woody Allen to write the screenplay with the intention that  it would be shot at the house. Unfortunately, by the time Allen  finished the screenplay, it was winter and the location was unusable  for a movie so firmly planted in September. The entire movie (which  takes place in Vermont) was shot on a single soundstage at the  Kaufman Astoria Studios in New York.
