Los pecados de una chica casi decente

This is a very funny movie if you like the Spanish comedies from the mid-70's (which I do). The whole movie takes place more or less in the same room, so it's rather like a filmed theatrical performance. The actors are two of the funniest Spanish actors ever, Lina Morgan and Alfredo Landa. This film was made during the "Apertura", a period in Spain when the transition from Franco to democracy took place. Almost every Spanish film from these years is about sex, this one too, but in a most decent way. Anyway, I think you will have to understand Spanish to enjoy it, as I doubt it will ever be translated.
