I've read a lot of Terry Pratchett's stuff, probably from when I was, like, 14.
So many different countries have got their version of what Merlin is: the Scottish say he Scottish, the Welsh say he's Welsh, the French say he's French.
Merlin is the unsung hero who is often responsible for things turning out positively, but rarely gets credit for that.
The big, big block in the Arthur/Merlin friendship is the status issue, that Merlin is the servant and Arthur is royalty, and in that time, princes did not socialize with their servants; that wasn't the done thing. It just so happens that their relationship, their friendship, is strong: they have been through the thick and the thin of it all.
For me, one of my favorites, director-wise, is Tim Burton. I also really admire the work of actors like Sean Penn. He is probably my favorite actor because of his dedication and commitment to roles, and the ability to morph and change himself when he needs to. It's about dedication and commitment and a passion.
I can't actually pinpoint anything that made me want to be an actor - I just did. And then anything after that just fueled it.
