Game of Thrones Season 5 Update: Cast and Plot Rumors, Martin Says Fans Have Accurately Guessed the Series' Ending

Season five of "Game of Thrones" is still being filmed, but already the rumor mill is flying as new casting information comes to light as well as some important plot points which have been revealed. The show is expected to end after two more seasons, with a final set of shows in Season 7.

The show's creators have already met with the "Game of Thrones" book author, George R.R. Martin to try and come up with ideas for the show's ending. However, Martin has said that he's still working on it. "I can give them the broad strokes of what I intend to write, but the details aren't there yet," Martin told Vanity Fair. "I'm hopeful that I can not let them catch up with me," he said refering to the television show producers. 

Later, Martin said at a recent book festival that a few astute fans have caught on to how he will end the book. While he didn't reveal the details, he did say that he's been planting hints in this fiction over the past four years and that a few fans have figured it out. There's been speculation that the ending could show Some fans believe the series will end with Daenery's ruling the kingdom with Jon Snow by her side.  But it's still way too early to tell. 

But, as the Guardian points out, maybe that guess is on the right track, "Why did Martin call his book A Song of Ice and Fire, they ask? Because Jon is ice to Daenerys's fire (she has been raising fire-breathing dragons during exile, you see)."

According to the website Winteriscoming.net, the locations for Braavos are hiring actors to play sailors, setting up the idea that there will be a big nautical battle in the coming season. Other reports suggest a battle arena being built in Spain that could be used for a battle to overthrow the dragon queen Daenerys.

With a series budget that averages about $6 million per episode, according to reports, the fifth season is expected to bring with it more action and adventure for the popular show. And a new location, actually based in Spain, will represent the fictional lands of Dorne, home to the Martell clan. The Martell plot line will play out with a look at the separatist kingdom's struggle for power.

There will also be a plot line that will reportedly involve trying to take over Daenerys Targaryen's floundering kingdom, that could include and attack by the Yunkai armies.

According to a report on Vulture, a slew of details have been confirmed about the upcoming season. For starters, the infamous Sand Snakes will be played by Keisha Castle-Hughes who will play Obara Sand, and Jessica Henwick will play Nymeria Sand. The actor Toby Sebastian will play Trystane Martell, Rosabell Laurenti Sellers will play Tyene Sand and the well known actor Jonathan Pryce will play High Sparrow, who is known as the High Septon of the Faith of the Seven.
