I had a strong, slightly illicit, urge to commandeer the original train sequence from the 1931 film Possessed and make it move in such a way as to give the girl (Joan Crawford) what she thought she wanted: a position on the inside. To do that, I had to create my own (all encompassing) vehicle. By my count, the original sequence provides three orders of motion: the motion (and stillness) of the passengers on the train, the motion of the train itself, and finally the motion of the girl (Joan) outside of the train.
