The writer Richard Curtis is a genius.

So, to me, it does shift, but it goes round. It just keeps going round and round and round. So if you have the longevity you have the belief and you have the resources to just keep at it you just ignore all that and just keep going where you're at.

Now there's always exceptions to that and the reason is if the film doesn't really work, whereas before you could rely on a decent amount of DVD sales to prop up the revenue to ensure that you got out in a decent manner, now if the film doesn't work, the film doesn't work and there's none of that DVD revenue to fall back on and you can lose a huge, huge sum of money on a big budget movie.

That middle ground of films used to be 70, 80, 90, 100; now it's like anything over 20 or under 140, the middle ground has become this huge area where they don't really want to be.

There's always that possibility. But, it would take a hell of a lot of work. Because unlike a movie where you just have to do a little ADR and then some mixing, we've actually got to bring the orchestra back because there is music, as you probably noticed, right the way through the film so you have to orchestrate all of that extra time.

I think everyone's going to really try to keep costs down. The more you keep costs down, the more freedom you have creatively. I can protect my filmmakers from any form of creative interference, be it from anywhere, if we're all acting in a responsible way and making the pain of a failure be as little as possible.
