"The Descent" and "Doomsday" filmmaker Neil Marshall is returning to Westeros.
Brought in at the last minute and given just one month to pull it off, it's a testament to Marshall's skill that his second season episode of "Blackwater" is still considered arguably the best hour of HBO's fantasy drama series "Game of Thrones" to air so far.
Now, Marshall is coming back for the show's fourth season to tackle the season finale. Unlike with "Blackwater," Marshall is getting plenty of time to pull off this episode. In fact, he's already in pre-production in London and Ireland on the episode which will shoot near the end of the year.
