As you read the books I'm sure everybody pictures a certain character different in their heads from other people but usually as actors or people you know. I thought it would be fun to see how folks envisioned certain characters.
For example:
To me I always pictured Travon Dumar looking like Pete Postlethwaite who played Kobayashi in the Usual Suspects.
Tug I always saw as Alec Guiness.
Telles is Dolph Lundgren
Steve
Really hard to do this to be honest. It's like a dream when I read books and they don't quite have faces you recognise. If I were scripting for a TV series based on these books. This is who I have in mind image wise.
To be honest, its been so long since I read the initial descriptions of these characters if their were any apart from age.
Nathan - Jake gyllenhaal (Though if we were talking about making this a real movie zachary quinto would nail this role. I know Nathan is younger than both, but he acts so old sometimes a 20ish actor would struggle to get this right)
Jessica - Someone like Michelle Rogriguez not quite her, more petite.
Vlad - Russian Ray Stevenson
President Scott - Bryan Cranston
Deliza - Natalie Dormer (As of part 2)
Josh - Taron Edgerton
Loki - Daniel Portman
Tug as Alec Guiness? Really? He wasn't that old surely....
Caius is Charlie Sheen so Tug can't be Alec Guiness.
Dumar - I get a more Keifer Sutherland vibe from him (secret family man, leader and capable of doing what he must for the greater good)
Telles - I get your imagery, but definitely not that actor personality and voice wise.
