Saw the clip from this movie back in maybe August 2012 when travelling in the States. It was a group of friends driving along a long road in the middle of a plain. It must’ve been halfway through the movie.

Up ahead they think there is a storm, but as they get closer they realise its just lots of bugs (locusts or grasshoppers I think). They’re all screaming as one by one the bugs pop through the air vents and begin swarming the inside of the car. That’s all I remember.
