Agent Pendergast -Can you imagine the actor to play him?

Holy cow, I love Pendergast. I've been reading those books for years. If I had to choose an actor to play him, Crispin Glover. If he dyed his hair. He's tall and pale and intense, and a little creepy, like Pendergast. But I have a feeling no one would be able to live up to the readers' expectations.
