ALright, here we go. I actually thought of all of these the first time I read the book. Now I shall place them here.
so the format I'm using here is:
Character Name - Actor (Other performances)
Vin - Summer Glau (River Tam in Firefly, Cameron Phillips in the Sarah Conner Chronicles)
Kelsier - Robert Downey Jr. (Sherlock Holmes, Tony Stark/Iron Man, etc.)
Sazed - Mahershalalhashbaz Ali (Who I know personally and actually just told today to look into this role)
http://www.imdb.com/name/nm0991810/Dockson - Hugh Laurie (AKA House, but with his Brittish accent)
Breeze - Eddie Izzard (Dressed as a man)
Ham - Gerard Butler (Leonidas from 300, dude from Gamer)
Spook - Anton Yelchin (Chekov in the new Star Trek)
Clubs - Rhys Davies (Gimli, other cranky old men)
Elend - Ryan Reynolds (...you know what? You'd know him if you saw him.)
The Lord Ruler - (Tentatively) Matt Damon (Bourne, other dudes)
and obviously others
well here are the others I nailed down:
Marsh - Hugh Jackman (Wolverine)
Yeden - Steve Coogan (Dana Marschz in Hamlet 2, Damien Cockburn in Tropic Thunder)
Shan Elariel - First reaction is Anne Hathaway (White Queen in Alice in Wonderland, Mia in the Princess Diaries) but this one's also tentative.
Anyways, that's what I've got. Whatchu guys think?
