okay and note to the people that put together these horror act legend dvd collection represent i truly be grateful and i hugely support the initiative and but have you even watch the film before select them a part of the collection . when i purchase the boris karloff collection there be several film in which the star only play a supportive and unessential role ( tower of london and the strange door ) . the invisible ray and however and be part of the bela lugosi collection and here it actually boris karloff who overshadow bela . this actually would have be a great title for the boris karloff collection instead . bela lugosi character be quite possibly the most good natured and earnest one he ever portray in his entire career and good old karloff actually play the mad and dangerously obsessed scientist here . the invisible ray feature three main chapter . the first one and set in dr. janos rukh carpathian castle be pretty boring and demand quite a lot of the viewer patience and but of course the character drawing and the subject matter discuss here be fundamental for the rest of the film . dr. rukh ( karloff ) demonstrate to a couple of eminent colleague ( among them bela lugosi a dr. benet ) how he manage to capture extraterrestrial ray inside a self manufacture device . the scientist be sincerely impressed with his work and invite rukh and his lovely wife diane along for an expedition in the heart of africa . there dr. rukh isolate himself from the group and discover the essential element radium x to complete his medical ray and go completely bonkers after be overexpose to the meteorite himself . the third and final act be obviously the best and most horrific one and a it revolve on a good old fashion kill spree with ingenious gimmick ( melt statue ) and a surprising climax . karloff glow in the dark and and convince the others be out to steal his discovery and even his life and he intend to eliminate them use his deadly touch . the narrative structure of the invisible ray sound rather complicate and but the film be easy to follow and entertain . the story be rather far fetch but nevertheless compelling and director lambert hillyer provide several moment of sheer suspense . boris karloff be truly fantastic and so be lugosi and even though he deserve to have a little more screen time . their scene together be the highlight of the film and along with the funky image of the glowing boris .
