I loved this Hammer sci fi film from the 50's..................I even liked it better than the first one in the series which is saying quite a lot.The producers convinced Shell Oil to let them film large parts of the movie at a refinery................this gives the movie a level of realism that its 90000 pound budget could never have purchased.What is all this hate directed ar Brian Donlevy..............lol..... he is fantastic in both films..............do check out the commentary for stories about his drinking and toupe..................fun stuff! Needless to say: highest recommendation!
