FWIW, they made Jessica Simpson lose over 30lbs for Dukes, so that see her skeleton bit while she was in the bikini isn't her "real" body.
I would have preferred it if they let her keep the weight on so as to not look malnourished... but whatever.
BTW, I think the movie was FUN.. simple as that. I never watched the show, so I'm sure that has something to do with it, but it was a blast to watch.
