A while back I saw this old school movie on a channel called cine latino and I don't remember what its called, but its about a couple that I think live in spain and they live in some apartments, basically what happens is that the wife and husband start making adult videos of themselves and they start becoming famous, well as they get famous a movie director contacts them and tells them that he wants to do a movie but only with her in it and basically they go with it until they read the script and see that the wife has a sex scene with another guy and he doest want her to do it but she thinks that he wants her to do it and she ends up doing it and that's all I remember.:)

Not to descriptive but hopefully someone knows what I'm talking about...

Not sure, but maybe Torremolinos 73 (2003) (http://www.imdb.com/title/tt0339806/)
