What's the biggest box office bomb ever?

Yahoo answers the question: What's the biggest box office bomb ever? Yes, Eddie Murphy's "Pluto Nash" wins top honors, though it seems like only yesterday the title was held by "Ishtar" or "Town and Country" or "Heaven's Gate" or "Cutthroat Island," all of whose directors (that would be Elaine May, Peter Chelsom, Michael Cimino, and Renny Harlin) give sighs of relief as newer and more expensive duds come along to move them further down the list. Yahoo! doesn't mention it, but this site has some terrific data about the most and least profitable films of all time.
