What has always been most interesting about acting to me personally is that it affords you the chance to shift gears, both in terms of the experiences you get to have through doing it, but also the different kinds of things you get to represent.
There is a lot of interesting product coming to market already. Bags and bottles and cups and such made of potato starch and other fully biodegradable materials. In some sense, plastic is more chemically complex. We ought to be able to simplify.
The deeper you go with the character, the more you see the layers start to peel away. It's more challenging to me, but it's also just interesting. Those are the things I like to watch. I like to watch the evolutions of something.
Sometimes their oppression of emotion and the weird way it comes out is more interesting than painting it in bold primary colors.
If you try to make interesting films, you're going to be disappointed most of the time. I choose just not to look at it that way.
I tend to relate to a character in terms of the arc: what's interesting is where he starts versus where he ends up.
