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. ("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.
