Paradise Highway

Juliette Binoche came over to the US more than a year before filming to start learning how to drive an American truck.

Sally always shuts her engine down every time she stops. This isn't the way truckers treat the big diesels in their trucks. It takes much more fuel to start an engine like those than it does to just let it run. Another factor is that a shut down and restart also causes excess wear as the engine returns to operating temperature, so starts are kept to a minimum on a trip, with the engine kept running sometimes for days at a time.
