Not that I've read it but it's a female targeted porn (sorry romance) novel isn't it ? Seems a weird thing to make a film of. Is it the kind of thing that will attract loads of women to the cinema where the film and not imagination has to provide the naughty ?
apropos of --something, B&Q have instructed their staff not to snigger when customers ask for rope and/or masking tape. Apparently there is an increase in buying these items because of this film.
