James Hibberd gets another scoop for EW, revealing the full list of directors for the 4th season, and clarifying the writer situation. Per Hibberd, here’s the directors:
Episode 1: David Benioff & D.B. Weiss
Episodes 2, 3, 8, 10: Alex Graves
Episodes 4, 5: Michelle MacLaren
Episodes 6, 7: Alik Sakharov
Episodes 9: Neil Marshall
As to writers, it looks like this season Benioff and Weiss are writing seven of the episodes this season—just as they did in the first season—while GRRM gives his usual single episode contribution, and Bryan Cogman now providing two episodes (huzzah!)
