Joseph Gordon-Levitt, a gym, tan, laundry-loving porn addict who loves singing Marky Mark songs?
That's the case in Don Jon
, the new romantic comedy written and directed by the actor. In it, he plays Jon "Don Jon" Martello, a club-hopping gym rat who cares about "my body, my pad, my ride, my family, my church, my boys, my girls and my porn."
That is, until he meets Barbara (a gum-chewing, leather jacket-wearing Scarlett Johansson
), who's obsessed with a different kind of guy-on-girl film – rom-coms.
Before Don Jon
's September 27 premiere, check out Jon and Barbara's one-month anniversary (aka meet-the-friends date
, as demanded by Barbara) in this exclusive clip!
