Looking for 70's or 80's scifi movie
The part I remember is a group of people, possibly being chased, traveling around in a converted mack truck and trailor. Throughout the travels they encounter toxic clouds, and the passengers have to don gas masks that the driver manually pumps O2 into. One of the passengers is an ex-scientist that caused these toxic clouds. He is in hidding and has had plastic surgury, but the driver knows who he is because of his eyes. I think they called them Zander Clouds. That's all I got... Saw it when I was a kid... any help would be great... Thanks Matt
