The writer Richard Curtis is a genius.

Then something fails and they're all out again, but DVD revenue is disappearing, you know, it's not disappearing but it's going off a cliff and what that's done is it's polarized the industry in a way that I've never seen before where studios are making less, they're bifurcating their choices where they're either going very, very big or they're just picking up a few rights on an acquisition basis or making really small things.

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.

So that is new in terms of where I've seen the shifts. Otherwise, it's all about taste and taste just keeps going round and round and round.

For us in England, the relative value of the pound against the dollar, that has a huge impact on how easy it is to get our films made in the U.K.

The shifts happen on a regular basis, but it's like a cycle. So things come in and out of vogue and then five years later they're back in vogue. Or there seems to be a theory that this is the way the industry will go and everybody goes over that way and then something happens to the country and you're back again at the place you were.

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.
