Being an avid fan of A Song of Ice and Fire, I've had fun pitching marketing ideas for Game of Thrones, both season 1 and 2. Lot's of ideas are pitched by several designers and artists from several agencies, so I don't get my hopes up that any one will win through, but I thought this one had a chance:
In the second book, the characters are spread out all over Westeros, so I thought it would be cool to show our characters standing on a large, room-sized map of Westeros (perhaps like the map at Dragonstone) at their approximate location. There would be a series of ads with photos taken from various locations. All would be of the same group, but focusing on different characters due to the vantage point -Dani from the southeast, Jon from the North, Tyrion from the Southwest, and so on. Furthermore the photos could correspond to a fly around bumper/commercial for the show. Well, this one didn't make it through either, so I can share it with you!
