The winter mountain scenes (filmed in Sun Valley, Idaho) started filming in the early winter. Unfortunately, there was no snow on the ground at the time. Several scenes were filmed with manmade snow. After filming these scenes, over a foot of natural snow feel the next day. Some of the scenes were re-shot in the "natural" background.
Considered to be one of the biggest box office disasters of all time. The Adventures of Pluto Nash (2002) is the largest in terms of financial loss with a budget of $100 million and a domestic gross of $4.41 million. Town & Country cost around $90 million to make, and it pulled in only $6.7 million (domestically) at the box office.
Buck Henry was hired for what was originally only going to be a few weeks of polish work. Eventually, he stayed on for several months and ended up earning (by some accounts) $3 million for rewriting roughly half of the script. Henry has stated that he bought a new home with the money he made on this "quick rewrite assignment".
Filming was originally supposed to wrap by the fall of 1998 for a summer or fall 1999 release. Various problems occurred during filming, however, including Warren Beatty's meticulous demand for many takes.
Reshoots were scheduled to begin on April 10, 2000, and expected to last just a couple of weeks. However, filming continued through June 2000, when it finally wrapped two years after principal photography originally began. The reshoots included all of the new scenes with screenwriter Buck Henry joining the cast as a divorce mediator. A new climax at a fashion gala involving all of the main female characters was written and filmed. Also the closure scenes with Garry Shandling and Goldie Hawn at the antique store and the scene with Warren Beatty and Nastassja Kinski on the street near the end were added. The scene between Beatty and Kinski in Manhattan as she's hailing a cab was actually filmed in downtown Los Angeles and was one of the last scenes filmed.
