Has anyone ever done a large scale fire scene? I was thinking ( which always gets me in trouble) that one of the silos in the barn would make a perfect furnace. The entryway could be where the bodies of the bad people get stuffed in and the silo itself could be the furnace. Kind of a hell scene if you can picture it. Apparently it can be done with fog and fans but I can't seem to find any detailed info on actual construction. Ant input greatly appreciated.
