  I don't know the movie but theater fires started by 
overheated film were not uncommon. There were also a couple 
of large fires at movie labratories and at studios from the 
same cause. Motion picture projectors had all sorts of 
safety devices on them. There were buckle trips to stop the 
machine if the film broke, an automatic douser on the 
lamphouse to close it off in case of broken film. The entire 
machine was enclosed and the film passed through tight 
rollers between the upper magazine and the projector proper, 
and again when leaving the projector and going into the take 
up magazine. There were mechanical heat fuses over each 
machine set up to trip the iron shutters over the projection 
ports and start fire sprinklers. The theater fires which 
inspired all this were absolutely dreadful. The public got a 
wake up call big time and demanded some sort of safety.
  Most of the directors of phography were sorry to seen 
nitrate stock go because it had excellent clarity where 
acetate sometimes could be seen to "boil" a little. Oh, 
well, it will all be digital soon.
