Trailer for Joseph Gordon-Levitt's directorial debut 'Don Jon' released - watch
Gordon Levitt also stars in the quirky romcom opposite Scarlett Johansson
As well as directing and writing the film's script, Gordon-Levitt stars as Jon Martello, a body-conscious womaniser whose friends call him Don Jon because of his ability to score with the opposite sex.
"Don Jon" enjoys porn even more than pulling, but attempts to turn over a new leaf when he meets Scarlett Johansson's Barbara Sugarman, an attractive young woman who prefers Hollywood romcoms to dirty movies.
The film's cast also includes Julianne Moore and Tony Danza. Meanwhile, Anne Hathaway, Channing Tatum and Cuba Gooding Jr all make knowing cameos as the stars of a movie within a movie.
Don Jon premiered at the Sundance Film Festival in January (2013) to generally positive reviews and opens in US cinemas on October 18. Its UK release date has yet to be confirmed.
