We're not one thing, as human beings, so any character that is written uni-dimensional, that's just a shallow character with shallow writing and shallow acting.
I remember in Shallow Grave I remember a few times when we'd only have to do one take. But when you did have to do more than one, you'd build on the one you'd done.
In the shallow parts of many Swiss lakes, where there is a depth of no more than from 5 to 15 feet of water, ancient wooden piles are observed at the bottom sometimes worn down to the surface of the mud, sometimes projecting slightly above it.
I've been a swimmer and a diver for quite a while. It was something that I think I got too comfortable with, and I dove into my black-bottomed pool and hit the slope from the shallow end to the deep end. And I had a chin to chest paralyzing break.
