I love acting. I think that's the best job in the world, but I don't really enjoy the career of it so much. You don't have as much control over your life or the material as you do, well, certainly when you're a director or a producer, so while I love acting, I prefer to make my living as a filmmaker, but my rule on acting is if somebody asks me to do a part, I'll do it.

To turn a human being into a part-canine or lupine creature takes a good deal of artistry and money.

You can argue that the Terminator movies reboot their world each time they go back in time, but that doesn't negate the value of Terminator 1 and 2. So I don't really feel that way.

While the storytelling in games is getting so much better, you look at something like Grand Theft Auto V, which I thought was really beautifully written, it doesn't really need a movie because it is a movie. So I think you need a unique game - you either need an incredibly talented writer and director to come in and put together an amazing vision, or you need a game like Metal Gear, which is very cinematic, has a huge amount of history behind it, but whose cinematic experience is very different from what you'd get in a theater.

Comic books, if you're adapting a comic book - like X-Men, for example - you've got 40 years of amazing stories to dig into, things that incredible artists have been thinking about for decades.

The most challenging work is producing. The physical act of getting a production up and running is extremely taxing, and you never have any guarantee that your years of work on any given project will ever bear fruit.

I think American Werewolf in London is the greatest werewolf movie of all time.
