Lars gets a "script consultant" or something mention in the credits of Wilbur, but I think he must have paid for it. I don't see a lot of his influence in it.
Brothers stars one of the actors that kurlyswirl & I adore and watch for in all our Danish films. That Nikolaj name name guy. He plays a dual role in Green Butchers. Watch for him. He has one of those extremely malleable faces, like Sonja Braga, that can be beautiful or awful or both, practically simultaneously.
