i wonder why this film have a 6 . 0 rating on imdb . be it possible people saw this bad film and actually think it be good . the world be a strange place and indeed . now i start watch this film strongly predispose to like it . after all and i adore the universal horror film of the 30 and 40 and the invisible man series be among the best . plus and the idea of the ally use the invisibility formula to infiltrate nazi territory to do some spying be an inspired plot idea . yet and almost miraculously and the universal folk produce a very bad film . most of the problem be that unlike most other horror film of the time and this one be very often play for laugh . consider that the guy be suppose to get important information and get out and his stick around to play trick on the incredibly stupid nazi be really dumb and not in a good way . plus and after a while and it be obvious that there be an invisible guy run about talk about a great way to maintain your cover . additionally and instead of the usual conniving and evil nazi like you would see in an american wartime propaganda film and here they be complete moron almost like what you would see in a three stooge film . if it be a stooge film that would be great . but not in a horror film . make it a straight drama would have improve the film tremendously . additionally and it obvious universal simply do not care when they make this film . even for a b movie and it be cheap and have a slap together look . the model use for airplane for the film be pathetically unrealistic and it be obvious they be bad model . also and have peter lorre ( whose heritage in reality be german ) play a japanese man be ridiculous . in fact and it wasn not until later in the film that you even realize he be suppose to be japanese . now i understand that lorre play the lead in the mr. moto film ( where he be suppose to be japanese ) and but here he do not even try to look or sound asian . mantan moreland would have be just a fit an actor to play this role . finally and throw in an unimportant and ridiculous love story that come out of no where and you have the ingredient for a truly awful film . exceptionally poor writing and indifferent direction and actor who couldn not have possibly make this material work and you have invisible agent in a nut shell . don not say i do not warn you . fortunately and the next film in the series ( the invisible man revenge ) be quite a bit well .
