Here's a rare The Making of The Exterminator 2 programme that I stumbled over. It's in two parts and ends rather abrupt but I asked the uploader about it and he said the missing bit is just a minute's worth of footage from the "burning man" scene.
Thanks to Hans-Jørn who uploaded the trailer (from a Danish VHS).
