Trailer Debut: Don Jon

Joseph Gordon-Levitt stars as a porn-obsessed body builder who must choose between his predilection for adult videos and a new girlfriend, played by Scarlett Johansson, in Don Jon.

The trailer for Gordon-Levitt’s feature directorial debut plays up the comedic aspects of the premise, which is smart, because taking that conflict even a little seriously would be a bad idea.

Originally titled Don Jon’s Addiction when it debuted at Sundance, it received decent notices. It will be interesting to see how audiences respond to this, ahem, mature (or should that be immature) romantic comedy.

It also stars Tony Danza, and features Anne Hathaway and Channing Tatum as actors in a fictional movie glimpsed in this very trailer (it looks very emotional).

Don Jon does not yet have a local release date.
