This is quite an undertaking—and even a bit of a surprise—for Joseph Gordon-Levitt, who wrote, directed and stars in this film. As the title implies, it’s a 21st century take on the fabled lover, Don Juan. Jon (Gordon-Levitt's character) is a somewhat self-centered guido, whose major detraction (for girls anyway) is that he’s a major online porn freak. He prides himself on how much tissue paper he uses daily with his…hobby. Then along comes the “10,” played masterfully by Scarlett Johansson, the one who discovers his obsession and demands he quit. All of this could’ve been handled in a much less challenging way for the viewer, but kudos must be given to Gordon-Levitt for a pretty damn good script. Oh, and Tony Danza even gets a thumbs-up as Jon’s dad.
