Right, that does sound quite messy. It's quite easy to determine some things (the Silmarillion and Hobbit book are mostly self-contained, and if the video game is Lord of the Rings Online then that's likely game-only characters as well since there aren't any significant differences when it comes to book characters there so it wouldn't make much sense to nominate them in that category), but book vs. movie often comes with strong opinions, so it's best to try and find a compromise. I'm a little disappointed that it won't be possible to see the Tolkien nominations, but guess that's just how it is. :/

At any rate, I'll be happy to help if that becomes necessary.
