Actually, the mention of Australian accents relied me of a New Zealand actor who is pretty good at doing other accents, namely
Alan Dale, one of those guys whose name you probably don't recognise but then you look at a picture and go, "Oh,
him". Recently he's been in
24 and
Lost, was a regular on
The OC and has a recurring role on
Ugly Betty. He could be reasonable in the adaption, perhaps as Kevan, if not Tywin himself?
