When I was in Cuba I found it curious that receiving U.S. television was illegal but American movies were shown in the theaters (this one must be 'You Don't Know Jack' with Al Pacino). When I asked my guide about it, he explained to me that no happy U.S. movies were ever playing and that only the dark ones with depressing topics been selected. I can't say if I was told the truth, but my source did sound very trustworthy.
