Having some fun with his co-star, Joseph Gordon-Levitt posed for pictures at the Sundance Film Festival on Saturday (January 19) in Park City, Utah.

Handsome in jeans, a maroon shirt, and tie, the “Don Jon's Addiction” hottie shared the spotlight with his on-screen father, Tony Danza.

Also starring Scarlett Johansson and Julianne Moore, the film was written and directed by Mr. Gordon-Levitt himself.

Sharing his thoughts about the plot, the 31-year-old said, "What I find often gets in the way of love is how people objectify each other and put expectations on each other that they've learned from different places. So the story centers on a relationship between a guy who watches too much porn and a girl who watches too many Hollywood romantic comedies, and I find that kind of thing hilarious so I wrote a comedy about it."
