My favorite bit with Mickey (Tarkovsky) is when he is about to walk out the door and he gives that little look over his shoulder.
I had to go back and watch that. I tell ya, the lenghts friends and family will go to to help us no budget filmmakers. It's great your buddy jumped in like that and gave it a try. Even the most seasoned actors can pucker up a little when the cameras start rolling. Good for him for going for it.
