There goes the J-Lo option lol, who do you think would, make the best susan?

I'm afraid I'm totally not seeing Scarlett Johanson as Murphy...she's way too glammy (and tall) and honestly I don't care much for her acting, either. She's pretty for sure and I thought she did a decent job in "The Prestige" with Hugh Jackman and Christian Bale but she just isn't Murphy to me.

You might have a point about the glam thing, but she is very short. 5'3 at most.
Also maybe throw some Eva Mendez in there for Susan?

Saw a thread like this for CA but couldn't find one for DF so i'm starting one. :-)
So for that movie theatre that is your brain who do you envision playing which characters? And feel free to add characters i haven't mentioned yet. (there's so many to choose from in DF) Also no need to be bound by you know, reality. You can add the young version of someone who is now old and vice versa for example.

Harry Dresden- Adam Levine, from Maroon 5 > Same as the reason for Mab
Mab- Anne Vyalitsyna > Watch the official music vid for "Misery" by Maroon 5 and you'll know why ;-)
Murphy- Scarlet Johansen
Thomas- Chris Evans
Lord Raith- A younger Martin Sheen
Lara Raith- Sasha Grey (what?!? it fits perfectly)
Kincaid- Jason Statham
Lash- Leslie Bibb
Billy- Joseph Gordon-Levitt
Nicodemus- Michael C. Hall
Butters- Colin Hanks
Michael Carpenter- Maybe a slightly older Chris Egan ( i just loved him as David in "Kings")
Bob's voice- Robert Downey Jr :-D
Marcone- Joshua Jackson (Not the wimpy dawson's creek version the BA Fringe version, at least in terms of demeanor)
 Well that's all that comes to mind for now. Have fun with this, don't take it too seriously lol
