Harry - Neil Flynn (Wouldnt have thought of it, but after I read this... damn... fits)
Thomas - Jared Leto (Pretty Boy)
Bianca - Amy Lee of Evanesence
Ramierz - Wilmer Valderama
Marcone - Dude who plays the Devil in Reaper
Molly - Hard Choice, I would go with the Paige Chick from Xmen and Hard Candy
Ebenezer - Anthony Hopkins
Bob - Hugh Laurie, or Bruce Cambell
Morgan - Alan Rickman
Nicodemus - Christophen Walken Ala Prophecy
Just who I think (Posting again)
Neil Flynn - as Harry? I don't think I can see it at all. Especially if we're starting off with Storm Front. Flynn could maybe be future!Harry but only b/c he's 50
Thomas - I have already made up my mind on this
Bianca -- Good call! Amy Lee is pretty much Goth Queen of Gothonia, playing Bianca would only seal the deal.
Ramirez - After That 70's Show, I cannot ever see Wilmer Valderrama in a serious role. Ever. He pretty much screwed himself with the role he played on that show. For me at least, lol.
Marcone - Ray Wise! Thank you for affirming this! It's what I've been saying for a while now, lol.
Molly - Now I'm showing my ignorance... was she in the movies? I have no idea who you're talking about, seriously. All I know about who has to play Molly is that she's supposed to be naturally blonde (with the willingness to dye her hair with colors not normally found in nature), and she has to be 'tall and built like the proverbial brick house'... just like whoever is cast to play Charity. Except younger.
Ebenezer - Still not sure on this one. Anthony Hopkins has played some of the greatest, and some of the freakiest roles in the world, and not to say he's not completely awesome, but I'm not even sure he could pull off Eb's role.
Bob - Hugh Laurie is completely amazing and I adore him. Unfortunately, I feel the same toward Bruce Campbell. Both are awesome choices, and I don't wanna choose :-)
Morgan -- Alan Rickman scares the crap out of me as Severus Snape in the Potter movies. But I don't particularly think he's exactly Morgan-like.
Nicodemus - Bluebeard already gave me my Nicodemus with the awesomeness of Mark Sheppard
You forgot Murphy!
Not even kidding, I keep doing searches for tiny, ass-kicking blonde actresses, and Sarah Michelle Gellar pops up on every list. I'm beginning to think it should just be her, lol. And she's the right age ATM. Murphy's in her early thirties at the beginning of the series.
