Those who can't think about Westworld without transforming the word into "Westeros World," know that you are not alone.

Indeed, you may have company on the highest level: George R.R. Martin, author of the A Song of Ice and Fire novel series, the basis of HBO's Game of Thrones. In an interview with Entertainment Weekly, Westworld showrunners Jonathan Nolan and Lisa Joy revealed that Martin approached them about a crossover between the two HBO properties, pitching a "Westeros World" of sorts, populated by robot hosts based on character from Thrones. While Nolan and Joy said they are big fans of Martin's work, they also pointed out some problems with the premise.

"I need to believe that dragons are real," Joy said. "I want them to be a real thing. So as much as I love George, I can't lose that for myself."

Even if a Westeros World never comes to light, it's certainly possible that Westworld will dip into a fantasy realm at some point. The original 1973 Michael Crichton movie includes not just a Wild West theme park, but also parks set during the middle ages and the Roman Empire. For their part, Nolan and Joy have not ruled out the existence of Medieval World and Roman World in their plans for Westworld, so it's not impossible that some form of Thrones cameo could occur on the show.

Read on for more from the week in Game of Thrones:

** He's long gone from the Seven Kingdoms, but Richard Madden's days of thinking about Game of Thrones aren't far behind him. In an interview with THR this week, Madden discussed some of his upcoming projects, including Medici: Masters of Florence, and even fielded the possibility of a return to Thrones. How would that even be possible, considering Robb was murdered and subsequently beheaded during the Red Wedding? There's one possible answer that riffs on an unused storyline from the books. Check out the interview for Madden's stone-hearted answer.

** Beyond Madden, other Game of Thrones veterans and current players are lining up new gigs of their own. For instance, Peter Dinklage has signed on to star in I Think We're Alone Now, opposite Elle Fanning, a film about two of the only survivors of a mass extinction incident. 

** Likewise, Alex Graves has signed on to direct Mulan, the live-action film from Sony. Graves has directed six episodes of Thrones, including season four's head-smashing "The Mountain and the Viper" and finale "The Children."

** The High Sparrow is gone, not a moment too soon for some fans. But those who enjoyed Jonathan Pryce's pious villain can still see more of the actor lending gravitas to ridiculous situations, as the man bringing life to "Tweets That Sound Better Out Loud."

** With filming on season seven underway, several reports from the set have emerged, including one that suggests a long-lost character is finally set to sail back into the world of Westeros. What's more, reports from Watchers on the Wall include a possible return for another outlander of sorts, and an even more tantalizing (and SPOILERY) tease of Jon Snow interacting with some of Westeros' newest arrivals. Proceed with caution.

** Finally, New York magazine's Vulture put together an illuminating gallery that fleshes out the differences between Game of Thrones and A Song of Ice and Fire versions of the same characters. How does Jon Snow differ on the show versus the books? Visit the gallery for that answer and more.
