Actors Cameron Diaz and Jason Segel is the couple whose private sex tape accidentally makes it into the hands of all their friends in the movie, “Sex Tape”, directed by Jake Kasdan. The director says that he needed a little help understanding the technical know-how of amateur pornography and he admits to turning to YouPorn – the world’s most popular website for porn.

What Mr. Kasdan didn’t expect to find that amateur pornography is actually more sophisticated technically than what he thought – something he found interesting from an artistic perspective.
