The very first time we saw a reproduction of this image was in Sandra Petojevic's website dedi­cated to the movie and showing some pretty good photos. On the back of the original press prints of this scene still, the caption reads: "Monster on fire... In climatic scene in the underground dwellings of the evil Morlock creatures, one of the treacherous monsters becomes engulfed by fire."

Now the series seems to stop here since we've never seen higher reference numbers on the photos... The next two pictures have different references, though beginning also with "1755".
