"I'll be back. *COUGH* ... I hope ..."
Almost the entire movie was also shot after dusk, adding to its dark and gloomy tone. But why go through all that hassle? Because if they filmed at night, they would have had less of a chance of getting caught by the police and fined for filming without a permit, and they actually had a couple close calls. During the iconic scene where Ah-nold steals a car by punching through its window, it was just Cameron and Schwarzenegger filming by themselves on a suburban street, because on the off chance that they were busted, nobody else would get in trouble. And the actual final shot, where Sarah Connor drives away into the desert, was even riskier. They needed to wait until morning for the day to get hot enough for heat ripples. After not having seen another car on the road for hours, the first one to appear ... was a cop car. However, when the officer pulled over and asked for their filming permits, they lied and said they were doing a student project at UCLA. Remember kids, your student ID isn't just useful for discounts around town, it's also an alibi.
