Joseph Gordon-Levitt writes, directs and stars in Don Jon, a frank comedy about a sex addict who thinks porn is better than true romance.

Levitt is excellent and consistently funny as the title character, a Jersey boy who is quite the studโ€”yet he finds himself jerking off to Internet porn within mere minutes of having sex with a live woman.

His problem comes to the forefront when he meets Barbara (Scarlett Johansson), the first real love of his lifeโ€”a woman with high standards who doesnโ€™t approve of the porn thing.

Gordon-Levitt has given us something akin to a funnier Saturday Night Fever, with porn replacing disco. Yes, the movie is full of porn clips, so donโ€™t see it with kids or a first date, unless you and that first date have some sort of naughty understanding.

Julianne Moore is her usual excellent self in a supporting role, and the shock casting of Tony Danza as Donโ€™s dad proves smart; Danza gets to show some cinematic comedy chops. Kudos to Gordon-Levitt for giving the old dude a shot.

Johansson is great, playing a role that gives her a chance to have a lot more fun than she has had in most of her previous projects.

This is a triumph for Gordon-Levitt. At the moment, he has signed on to produce Neil Gaimanโ€™s Sandman for the big screen. I think he has some pretty good directing chops, so it would be nice to see him star in and direct the project as well.

Special Features: There are a couple of decent making-of doc, and some short films.
