That double Ed Norton in the title is not a typo; Leaves of Grass stars the talented actor in a dual role, as polar opposite twin brothers.
As twins, Norton really goes for it — one twin, Bill, is straight-laced, while the other, Brady, is a mulleted hick with a heavy Southern accent. I've missed Norton's presence, but I'm wondering if this is going to a be an amazing acting opportunity or an embarrassing diversion for him. Joining him in the cast sans outrageous accents is Keri Russell, Susan Sarandon, and Richard Dreyfuss. It's a little hard to tell the tone of the movie from the trailer; it's been described as a comedic thriller, but I can't tell if it wants to be Adaptation or Joe Dirt.
