Don JonJoseph Gordon Levitt [L] and Scarlett Johansson [R] In Don Jon

If you'd taken time to read any of the articles about Joseph Gordon-Levitt's directorial debut Don Jon, you would have been forgiven for assuming it was an expose of the dark side of porn addiction. It is that, but it's also a comedy and from the looks of the first trailer, a funny one at that.

As well as serving as writer-director, Gordon-Levitt also plays the movie's lead Jon Martello, a young guy who enjoys his swish apartment, working out, driving his car, going to church, socializing and...watching porn. Watching a lot of porn. His subsequent expectations of sexual relationships mean he is unable to build a long-lasting relationship with anyone, despite his friends dubbing him Don Jon for his ability to land any woman. 

Jon eventually meets a stunning blonde girl (Scarlett Johansson) at a club and arranges to meet her for a string of dates, rather than his usual one night stands. Things are going pretty well - until she catching him watching porn that is.

Watch the Don Jon trailer:

Don Jon  - previously titled Don Jon's Addiction - appears to be exactly what we expected from Gordon-Levitt's debut feature. Its slick, stylized and most evidently, funny. When Johansson's character makes the distinction between porn and movies - saying movies win awards - Jon's response is predictable but no less hilarious. This one could be very, very good.

Don Jon hits cinemas in the U.S on 18 October 2013 and in the UK on November 15, 2013. The supporting cast includes Julianne Moore and Tony Danza.
