I became a fan of Aitana Sanchez Gijon after watching her in Femme de Chambre du Titanic and that was the sole reason I chose to watch Boca a Boca (Mouth to Mouth). It stars Javier Bardem (who plays the role of Victor Ventura, a struggling actor) who takes a job as a phone sex operator to pay his bills before he appears for a casting call for a Hollywood movie. He ends up answering a phone call from a plastic surgeon (Bill or Ricardo played by Josep Maria Flotats) who is a down-low man (people like Ted Haggard who are supposedly happily married to a woman but are secretly gay) and in his desperate attempt to make as much money as possible, he makes Bill think that they are in love. But Victor is actually in love with Bill's wife Amanda (played by Aitana Sanchez Gijon) who sleeps with him to take revenge on her husband.
The plot gets complicated after that and I will not give you any more details but you have to wait till the end to figure out who was trying to kill who for what reason. All I can say is that it is not what you think. Despite what I have described above, the movie is fairly clean, but be warned that it is rated R due to the nature of the theme. In my opinion it is a beautiful comedy that would remind you of movies like Beverly Hills Cops. Strongly recommended.
