Tony Danza has joined the cast of the Untitled Joseph Gordon-Levitt Project, which was formerly known as Don Jon's Addiction. The actor will reunite with Joseph Gordon-Levitt for the first time since starring in the 1994 comedy Angels in the Outfield.

Joseph Gordon-Levitt will star as a womanizing porn addict, who goes on a quest to become less selfish. Scarlett Johansson will play his girlfriend, and Julianne Moore is portraying a widow who the main character meets at night school. Tony Danza is playing the lothario's father, who is obsessed with sports and doesn't pay enough attention to his children.

Joseph Gordon-Levitt will make his directorial debut, working from his own original screenplay. He will also produce alongside Ram Bergman and financier Nicolas Chartier, who is backing the project through his Voltage Pictures company.

Production will commence next month in Los Angeles.
