Whittling
A guy whittling on a train? This cracks me up.
It's not just the dinosaur security, that's too easy.
Creating a pile of wood shavings on the train. That spooks me. Did people in this country ever accept that?
Never ever ever seen whittling as a character definer before this film.
It allows Broderick the antagonist to walk around armed without the necessary premeditation of a killer but with all the same menace.
