I don't rember much about this movie but had a impact on me as a kid.It involved large locust and possibly the end of the world..near the end there was a large fire in one of the big cities(maybe new york/chicogo) there was a large firery face that resembled the devil and a man was on a fire truck ladder and swung the the ladder into the firery face.I only seen small parts of this show but the images were long lasting.Any help out there let me know I have tried various searchs at guessing cross references but aparently locust and the devil cross reference lots of times to lots of things.I viewed this show early to mid 70's and believ it was black and white
