"I've got a head for business and bod for sin." That was the famous line from this Melanie Griffith film. Note that her list of attributes doesn't include the ability to act. And while her 'bod' was for sin it wasn't remotely as attractive as the movie wants you to believe it is. Moreso than Sigourney Weaver, but that's a pretty low threshold.
This movie is ok at best and it's amazing that it got a nomination. (Actually, looking at the list of other nominees, the cupboard was rather bare. I still would have gone with 'Bull Durham' or 'Who Framed Roger Rabbit'. Probably even 'Diehard'.)
