I think once those friendships, if you use that as an analogy, the friendships between the audience and the character is established, then you can start to take liberties. I believe that as this unfolds people will find the time invested worthwhile.

I must have been about 11 when I read the book Bury My Heart at Wounded Knee, which I read, over and over again.

Suddenly, after years of television being the poor relation and film being everything, it now feels like film is a conjuring trick. It's like, "Oh, my god, how are you going to do that in 90 minutes, as opposed to eight hours?! I've got so little time to do this!" It becomes an art form, in itself. Doing both helps you do each one.

With FX in particular, they've been fantastic and were really hands off. I mean, it helps that you've got Ridley Scott on your side.

There [in Allied] were things that were written that were cut, and things that were shot that were cut, but if the film works, they are erased from memory.

I'm always interested in characters who are closed down, but who open up when they choose to, rather than when they're obliged to. I think that's a very appealing thing, for an audience and just in life. I like the idea that something will say nothing, and then get straight to the point. That feels like how your heroes should be.

I wouldn't put myself in that bracket, but it's one of those things. I think what helps is that we [with Tom Hardey] don't socialize, we don't really know each other, we purely work together.
