I got to attend the US premiere of Game of Thrones season 5 in San Francisco. Next thing I knew, I was talking to George R. R. Martin on the red (black, really) carpet. We talked about spoilers:
"I read a lot of historical fiction, you know? I know who won the Civil War — it's not a spoiler to me. But I can still enjoy Gettysburg, even though I know how the battle came out. I can still enjoy historical fiction about the Wars of the Roses, even though I know who won the Wars of the Roses. And for that matter, I still enjoy watching Citizen Kane every few years even though I know 'Rosebud' is the sled. So there — I just gave a terrible spoiler to all the people who haven't seen Citizen Kane. Rosebud is the sled, but nonetheless, you should still watch Citizen Kane, because it's incredible!" Martin laughed a deep, satisfied laugh, and continued down the black carpet.
