A synopsis from Anna Oms on the IMDb (Internet Movie Database) says:
Molina offered the EMT a blank version with just the film title but they refused that too which would seem to suggest that the word nymphomaniac was as much a problem as the image: Christian argues that had the 'N' word been 'assassin' there would have been no objections; one assumes he's correct and one assumes also that it would be the same with words like Terrorist, or 'Sex-pot' however some words do get a different reaction e.g. would advertising for a hypothetical 'Diary of a Paedophile' be banned? Would other such 'bad-buzz-words' also have been allowed? He goes on to say - with a touch of hyperbole methinks - that the EMT's action is reminiscent of the censurship suffered under Franco.
"Val is an attractive, well educated and well off 28 year old. Whats more shes very sexually liberated and constantly on the hunt for new encounters to satisfy her endless sexual curiosity and desire. She sleeps with whoever she wants, whenever she wants to, ending up making sex into a lifestyle; a lifestyle that leads her to find both love and a career in prostitution. In both she experiences the extreme." [sic]
Enough of that: in the film Catalan actress Belén Fabra (she played Olga in Canciones de amor en Lolita's Club) plays Val.
