Like 'Harry Potter and the Prisoner of Azkaban' before it, very often book to film-adaptations begin to grow increasingly disparate when directors reach the longer, meatier entries of the series. Such will prove the case with 'Game of Thrones' season 3, which adapts roughly half of series creator George R.R. Martin's novel "A Storm of Swords," incorporating a few elements from its sequel as well, but will it be long before the story changes create bigger problems? Find out what Martin has to say of the 'Game of Thrones' season 3 changes inside!

Though season 2 took a number of liberties with the 'Game of Throne's canon, HBO's upcoming release of 'Game of Thrones' season 3 could prove the most divergent yet. The season premiering March 31 purportedly covers around half of the George R.R. Martin book on which its based, but Martin himself has a bit of concern that HBO's adaptations under show-runners David Benioff and Dan Weiss could soon create larger problems in the story.

Martin spoke to Amazon’s Omnivoracious Blog of the upcoming season, acknowledging the necessary changes inherent with adaptation, but also teasing that upcoming episodes could have greater difficulties as a result:

I think [deviation]'s a process that’s likely to continue, and some of that is just the nature of the process. I mean, when you make...Everything is related to everything else. So, if you make a small change in Season 1, it could lead to a really big change in Season 4 because the thing that was supposed to happen didn’t happen and the guy who was supposed to come in never appeared and it was just a line in that book but now you’re in this later season and you don’t have him set up. So, everything gets magnified and you have to deal with it.

Martin also predictably explained that he still prefers the world of the books given the greater detail and breathing room allowed, but did concede that HBO's version occasionally impacts his thinking about future stories. In particular, Martin recalled his disapproval of actress Natalie Tena for the role of Osha as written, but quickly changed his mind upon viewing her performance, something that would perhaps linger in his mind when writing for the character in his novels going forward.

Fans of the series will be sure to observe any potential book-to-TV changes when 'Game of Thrones' premieres its third season on March 31, but what say you?
