UK actor John Simm has joined the as-yet-untitled Game of Thrones prequel.
Simm, well known for shows such as Life on Mars, Doctor Who and White Dragon joins Naomi Watts, Josh Whitehouse, Miranda Richardson, Naomi Ackie, Denise Gough, Jamie Campbell Bower, Sheila Atim, Ivanno Jeremiah, Georgie Henley, Alex Sharp and Toby Regbo.
Also announced this week are Marquis Rodriguez, Richard McCabe, John Heffernan and Dixie Egerickx.
Set thousands of years before the stories now unfolding, the prequel chronicles the world’s descent from the golden Age of Heroes into its darkest hour. And only one thing is for sure: from the horrifying secrets of Westeros’ history to the true origin of the White Walkers, the mysteries of the East to the Starks of legend… It’s not the story we think we know.
Co-created by filmmaker Jeanie Finlay, it begins filming mid year.
