Game Of Thrones: 10 Possible Plots For A Movie

7. White Walkers

This is probably the most off-the-wall suggestion, but the White Walkers clearly have a hierarchy system. They're a civilised race, more than just a thrown-together band of psychotic ice demons. How many are there? What do the others do? What is their purpose? A film with the Children of the Forest could incorporate this one, showing the battle from both sides, but with #TeamWhiteWalker ever-growing following the Season 5 finale, they could be enough to spark a whole production, however deathly quiet it may be.
