How the cast of Game of Thrones should really look

Casting can make or break a show, and that's particularly true when your series or movie is based off a popular book series. Cast the wrong actor or actress in a role, and you may have angry fans sharing their thoughts about your show all over the internet. When it comes to the beloved Game of Thrones, many of the characters don't exactly match what's written in George R.R. Martin's books—in fact, in a few circumstances, they don't match at all.

Sometimes for practical or storytelling reasons, it's necessary for producers and writers to change how someone looks. Let's take a side-by-side comparison of those Game of Thrones characters who don't quite live up to their novel namesakes, and what they should really look like. But fair warning—this list may contain spoilers for the entire Game of Thrones television series, as well as the A Song of Ice and Fire  books.
