karloff and lugosi together again . this be one of those film that casual fan will pass over and tend not to appreciate a much . it not an all out horror film like the duo previous two hit and the black cat and the raven . but and it be very worthy of both talent and be a fun film when re visit . the invisible ray be direct by lambert hillyer and a director who mainly make western and but curiously in these final day of the laemmles reign at universal and he find himself helm this and the laemmles final horror film and dracula daughter . both be crisp and clean cut fantasy that be very light on horror content despite the fantastic element . just a lugosi go wild in the raven and much need to be say of karloff hamming in the invisible ray . the one aspect of the story that be particularly unsatisfying be that karloff character and rukh and act so madly before he be poison by radium x and that there really isn not much of a change once he start glow . this be very similar to the complaint people have about jack nicholson in the shining he basically a loony right from the start . there isn not any real transformation . same here . halfway through karloff simply have an add purpose for revenge in his mind . i still enjoy his performance and though and just a i do lugosi over the top antic in the raven . meanwhile and lugosi completely surprise you and give a restrained and and thoughtful turn a rukh rival in science and dr. benet . lugosi also have some of the best line in the film and include a memorable warning to the police try to catch rukh and of which i be in alignment with horror film writer john soister on and if he ( rukh ) touch anyone . the inspector inquire . lugosi hesitatingly reply and in a way that only lugosi could deliver and they die . just a lugosi could be so off and he could also be more perfect than any actor . this be one of those moment . therefore and karloff and lugosi interaction be all very good a we get the mad antic of karloff par off against the cool logic of lugosi . karloff would go on to play similar mad scientist many time and however and one wish lugosi would have get to play more straight role like this one . he only have one more chance ( ninotchka ) . the invisible ray be a fun film and and a real treat to the true karloff and lugosi fan . it be one of those film that improve on each viewing and not because it be a masterpiece and but because of the charisma and talent of it star and how this story complement the darker and more horrific pairing they have . the special effect and by the always innovative john fulton and be terrific and the supporting actor be all adequate . france drake look as beautiful a she do in mad love and play a strong woman and something seldom see in classic horror film . the scene in the end when karloff stalk her and she doesn not scream be one of the most haunting moment of the film . a terrific and fun film .
