F1ach: I have read all except Dance of Dragons, I was kinda disappointed with the TV series, I thought Tyrion was well played and his dad, Sean Bean was very good too, but I wasnt crazy about the rest of the cast and....dire wolves played by...huskies?
Sean Bean played Eddard Stark, father to Robb, Sansa, Arya, Bran and Rickon Stark, and John Snow. Tyrion is a Lannister and his father, Tywin Lannister, is played by Charles Dance.
The dire wolf
pups (important detail there) were actually played by Northern Inuit dogs. One of the few complaints about season 1 by fans of the books was that the dire wolves were underused, and I agree. The creators explained that this was mainly due to budget/technical reasons -- ie. they did not have the money to do a proper CGI version of the wolves and thus did what they could with the dogs. The issue has also been addressed in several interviews regarding season 2, which presumably received a much larger budget, where the creators have acknowledged that they want the (now maturing) wolves to play a bigger role and be handled better, and most likely with CGI... just like a certain other trio of creatures that plays an integral part in the books.
I absolutely loved the first season and thought the casting was stellar. IMO it is the best fantasy production since Lord of the Rings and I can't wait for season 2 :-)
