I'm quite sure Shakespeare enjoyed writing Iago much more than he did writing Othello. If you write about someone you love, what the hell are you supposed to say about that person? It's much better to have something between you and your main character that grates.
I do remember being a fan of the Marvel characters and not liking the DC characters at all.
If I play a cop, it's always a racist cop or a trigger-happy cop or a crooked cop - but by and large I play cowboys, bikers, and convicts.
I'm going to try to play some good guys for a while and just see how that is. It's hard to enjoy them as much as the bad guys, and the clothes are nowhere near as good. Good guys don't wear nice suits!
Your character is always right. No real person thinks they're being stupid or misguided or bigoted or evil or just plain wrong - so your characters can't, either.
We often get pigeon-holed as a tough guy, or whatever else. I've been pigeon-holed as a heavy and serious, and almost a baddy, but not quite a baddy, over the years of my work in television, particularly.
River Song? Amy Pond? Hardly weak women. It's the exact opposite. You could accuse me of having a fetish for powerful, sexy women who like cheating people. That would be fair.
I don't have acknowledged preferences of characters.
One of the most beautiful things about 'Game of Thrones' is it's told from so many different points of view, and these characters can convince you that what they're doing is right. But they're only showing you a bit of the picture, and when you see it from another character's point of view you may switch allegiances.
You really have to get out of an actor's head to write because actors only care about their part and it revolves around their part so "This is the important part because this is the part where..." .
I've always thought darker characters were more fun to play. They're probably not any more complex or interesting than their good, law-abiding cousins, and I'd always tend to see things from their point of view.
