this be just about in the same league a ` the black cat and although i would give this a 9 rather than a 9 plus . that praise indeed for a film that have be so badly underrated that it be amaze . ` the invisible ray be part horror and part drama and certainly part sci fi . for a movie make in 1936 the sci fi element be a good deal ahead of their time . the mixture of horror and drama and sci fi be a perfect blend and while the act on the part of lugosi and karloff couldn not be good . director lambert hillyer capture a lot of element that jam whale do so often . what i be say be that this film be eerie and well shot . the scene with the gargoyle outside of lugosi room be a perfect example of the mood . it a standout moment in the film and which be so sadly miss in today movie of the genre . a with ` the black cat and ` island of lose soul and i can not understand why this film have yet to be release on dvd . when you consider some of the junk that already be transfer to dvd it that much more puzzling . anyway and watch this film if you get the chance . when it release on dvd grab it fast and put it in an honored spot within your dvd library .
