Despite my attitude during the shoot – which was a kind of strange, focused madness – nobody ever complained. They all knew it was dangerous and their reactions, for the most part, are real. I didn’t have to tell them to be afraid – they were terrified. It was actually the actors behind the wheel [of the trucks] most of the time. They were driving during the bridge crossing. If they had put their foot on the gas unintentionally, it really could have been a disaster. It was not as tightly-controlled as you would have to do a sequence like that today. There was a lot left to chance, and fortunately, nobody get injured at all.
