(CBS News) -- Scarlett Johansson and Joseph Gordon-Levitt are getting hot and heavy in "Don Jon."
The new film marks Gordon-Levitt's feature-length directorial debut. Aside from starring and directing, the "Dark Knight Rises" star also wrote the screenplay.
He plays the lead role of "Don" Jon, an Italian-American devoted to his family, friends, religion...and online pornography. His Web interests become so intense that it starts to become an addiction and, pretty soon, his girlfriend Barbara (Johansson) grows tired of his compulsion.
Johansson's character watches a lot of romantic comedies and thinks that their relationship should be like a Hollywood love story.
"They both have very rigid expectations that they're unwilling to part with," Gordon-Levitt said in an interview with CBSNews.com at the film's New York premiere on Thursday night. "And they've learned those expectations from all sorts of places. Their upbringing, their friends and family. But also from different kinds of media. And I think we learn a lot from what kind of media we let in to our eyes and our eyeballs. It's worth poking fun at."
Watch video above to see Gordon-Levitt, Johansson and their co-stars Julianne Moore and Tony Danza speak about the film on the red carpet. Danza reminisces about his days with a then-12-year-old Gordon-Levitt on the set of "Angels in the Outfield."
"Don Jon" opens in theaters on Sept. 27.
