eckhart totally fits the bill for me. but it's odd that this was mentioned:
I think Nathan Fillion a bit, if his hair is just right.
i watched slither for the first time today and found myself comparing this actor to james. weeeird. but like i said in another thread, i just pray that they don't screw up and have the main characters played by some shitty actors; or if they do plan to follow the sh2 storyline and don't do it exactly i'll probably cry.
