Town & Country (2001)
The cast of Town & Country was a veritable treasure trove of comic legends: Warren Beatty, Diane Keaton, Goldie Hawn, Andie MacDowell, and a laundry list of others. Still, after a debilitating 12 delayed releases, the weak script made this film one of the biggest flops of the 2000s, with estimated losses rounding up to $85 million.
