While Amazon's 'Lord of the Rings' is soaking up a lot of the media coverage, they've got another high-fantasy epic series in their arsenal to rival 'Game of Thrones'.

Robert Jordan's 'The Wheel of Time' was a 15-book series that ran from 1990 up until 2013, spanning two decades and the author's own passing in 2007. A TV series adaptation had been planned for years, but it's only now that it's finally happening thanks to Amazon Prime.

The series, which will be available on Amazon Prime and is expected in 2021, is set in a strange-but-familiar world where technology and magic clashes together and time itself is in a cyclical nature. It's all the typical high fantasy stuff you'd expect - reincarnation, promised heroes, wizards and dragons, prophecies - but it's got a legion of fans desperate to see it.

Much like 'Game of Thrones', Amazon is filing out 'The Wheel of Time' with a relatively unknown cast, other than Rosamund Pike as the lead. Barney Harris, Madeleine Madden, Josha Stradowski and Marcus Rutherford will play Mat Cauthon, Egwene Al'Vere, Rand Al'thor, and Perrin Aybara respectively. Pike, meanwhile, will play Moiraine Damodred, the sorcerer who sets out to find the Dragon Reborn.

The pilot episode is set to be directed Uta Briesewitz, who previously worked on the likes of 'Westworld', 'Altered Carbon', 'Orange Is The New Black' and more recently, the third season of 'Stranger Things'.

So far, no air date has been confirmed, but it's likely that 'The Wheel of Time' won't land on Amazon Prime until 2021.
