Kim Cattrall: Environmental Crusader?

In a bikini, winter jacket and Uggs no less.  We caught Kim Cattrall on the beach in Malibu, California where she was shooting scenes for the upcoming Sex and the City movie.  We're not exactly sure what this is all about; is she doing this on her own volition? Is this a scene from the movie?  Serving some community service hours in between shots? We may never know, but thanks anyways Kim!
