[Kitanna]

If Grima looked like a normal Rohan man (such as Eomer or Theoden) I'd have a hard time accepting that. I always thought of Grima as a slimy little worm and PJ's Grima looked like a slimy little worm.
Of course he could still have been that worm with blond hair, but him being short...well he's not really. He seems to be average height and sometimes he looks like he's walking hunched over. Grima's walk of cowardice.
