They look so different on the movie poster compared to the movie!

Anyone notice how different Emma Thompson and Jeff Goldblum look on the poster, compared to the actual film? I'm talking about the poster that is the picture for this movie on this site.

It makes me wonder, was this movie actually filmed more than one time? Because I notice a couple of people on this board have referenced a Miramax version of the film, as well as a UK version. And that leads me to question if that accounts for the differences in the way the characters look on the poster compared to the film I watched – which was the UK version.

Could somebody who's seen the Miramax version, please let me know? I would really appreciate it.

Or perhaps, anyone who has seen both versions – please let me know what differences there are. I am interested to know how they differ.

Please excuse typos/funny wording; I use speech-recognition that doesn't always recognize!
