When it comes to acting and directing, Joseph Gordon-Levitt is not the kind of individual who is afraid of taking risks.

In his latest film, "Don Jon," Gordon-Levitt stars as Jon, a confident bartender who loves his car, his apartment and women. However, all of these things pale in comparison to his love for Internet pornography.

The movie follows Jon's struggle with his addiction and how it affects his relationships with others. Throughout the film, Jon tries to hide his unhealthy habits from his needy girlfriend. Later, when his addiction seems to be tearing his life apart, he receives guidance and love from a middle-aged woman in his night-school class.

The film is Gordon-Levitt's directorial debut, and the innovative techniques he employs are enough to show that he is not afraid to work with such a controversial topic.

Gordon-Levitt gives the viewer a chance to hear the thoughts and feelings of Jon by narrating much of the movie from a first person point of view. In addition, the opening credits of "Don Jon" include flashes of racy images, and pieces of explicit pornographic videos are displayed throughout the entirety of the film in order to emphasize the severity of Jon's addiction.

The constant exposure to these images can be a bit shocking and awkward. Despite this crass representation of Jon's addiction, however, the casting of the film is quite excellent.

Scarlett Johansson does an excellent job portraying Jon's attractive, controlling girlfriend, Barbara Sugarman. Her interpretation of the character sheds light on how women may misinterpret the purpose of a significant other.

Julianne Moore adds a nice touch to the story as Esther, Jon's classmate and motivator. Her character plays a key role in Jon's recovery, and she explains the root of Jon's problem to the viewer as well.

The most outstanding performance, however, is that of Gordon-Levitt's. This character is much different from any role he has played before, so it allows him to demonstrate his flexibility as an actor. He also adds the right amount of humor to his role when he discusses his serious addiction throughout the movie.

In addition to having a great cast, "Don Jon" is making a name for itself by touching on the relationship issues that are attributed to having unrealistic expectations of one's significant other. In the film, Jon has unrealistic expectations of women based on his porn addiction, while Barbara has unrealistic expectations of men due to romantic comedies, which causes turmoil.

With a marvelous cast and a unique take on addiction, it's no surprise that the film has been successful. Gordon-Levitt has made a remarkable directorial debut, and it is obvious that creating "Don Jon" was a risk that was worth taking.
