This is typical 1950's B movie fare but I think it is a few notches above the rest. Ok, the acting is a bit hammy and campy even with the talents of John Agar, John Carradine and Jean Byron. The idea of the film is unique. Aliens, invisible to humans land on earth, inhabit the bodies of the dead to take over the planet. There are some stretches of boredom as frantic scientists and military personel try and figure out a way to combat the "invisible invaders", but at certain times this movie can give off a few chills. The reason for this is because at certain times, the movie resembles "Night Of The Living Dead" some 9 years earlier. The scenes of the "invaders" rumbling around as the recently revived dead are quite effective. The dead are almost as convincing as they were in "NOTLD". They roam around seemingly with no purpose though they do have one, arms outstreched, emotionless faces with darkened eyes. Quite effective and chilling in certain areas. Rest assured this movie is not "NOTLD" and pretty much is typical B fare but it does provide glimpses of a soon to come clasic and can give you a chill or two. I'd say rent it or better yet, buy it for your collection. It's fun!
