Relativity Media has released the first trailer for Joseph Gordon-Levitt’s directorial debut Don Jon.  Gordon-Levitt stars in the comedy as a contemporary, porn-addicted Don Juan-type who attempts to reform himself.  I caught the film at Sundance and it’s really funny and marks the start of what looks to be a very, very promising directorial career for Gordon-Levitt.  This trailer does a great job of conveying the film’s tone and the style that Gordon-Levitt has crafted, as quick editing, music, and repetition are used frequently to present some of the film’s situations, especially with regards to the porn.  While the trailer does give away a couple of the pic’s best comedic surprises (like the cameos), there’s also a sweet sincerity to Don Jon that’s only hinted at here, and the performances from Gordon-Levitt, Johansson, Moore, and Danza are all top-notch.  I expect the film will be a major crowd-pleaser when it hits theaters later this year.

Joseph Gordon-Levitt’s feature directorial debut Don Jon’s Addiction landed a record-breaking acquisition deal when Relativity picked it up after Sundance, but the pic is now getting a title change.  Simplified to Don Jon, the picture stars Gordon-Levitt as a contemporary, porn-addicted Don Juan-type who attempts to reform himself.  The film also stars Scarlett Johansson and Tony Danza.

Be sure to read Matt’s review here and hit the jump to see what Gordon-Levitt said on the topic of the title change, plus four new images.

Don Jon’s Addiction is much like its eponymous character: not much depth but quick, confident, amusing, and oddly endearing.  The entire film quickly boils down to its core concept in the span of its frenetic intro: the eponymous character is afraid of intimacy.  So who’s going to tear down that emotional wall?  How will he learn his lesson?  How can a lothario clearly based on “The Situation” from Jersey Shore ever learn to love?  Director, writer, and star Joseph Gordon-Levitt knows his character inside and out, backwards and forwards, and finds the sweet, vulnerable heart of a guy who keeps Kleenex in business.

Tony, Toni, Toni.  We’ve got three casting notes for you today featuring one for Tony Danza and two indies for Toni Collette.  Here they are at a glance:

• Tony Danza has been tapped for Jospeh Gordon-Levitt’s directorial debut, an untitled dark comedy that also stars Julianne Moore and Scarlett Johansson.
• Toni Collette is eyeing the indies Miss You Already and The Long Way Down.
