I'm probably one of the worst actors as far as preparation goes, because I actually don't prepare. I find it easier to read the script and whatever hits me in my stomach, like deep down, I just go with it. And the director kind of molds me whether to go right or left with it.
It is not necessarily true that expensive experiments are not worthwhile doing but there are plenty of rather cheap experiments which are certainly worth doing.
At the end of the day, we must go forward with hope and not backward by fear and division.
