There is so much to say about this terrible movie.I could write a review longer than the script but it's not worth my time. The trailer says "From The Depths Of Hell It Came,To Hold All Men Prisoner and Every Woman Slave!!" That's 100% false,it didn't do any of that. Not to mention that it's not a giant and they know where it's from..... This flick is so bad that the make-up "artist" gets his name in the opening credits and the make-up is just some dirt on the guys face. So anyway,a scientist and his daughter show up in some country town(sounds REAL familiar) and guess what?They immediately run into another scientist!!! Turns out the younger scientist was at a lecture given by the older one but the old guy doesn't remember.At the same time the sheriff shows up to hassle the old guy and warn him that the younger guy is probably a murderer, even though there's no evidence to support that. Most of the movie is spent using terrible writing and acting to get the characters to split up,it's silly. The old guy has come to town to search for artifacts to prove whites had been there centuries before Columbus and that one of them was a giant.After a few minutes of searching he decides to give up,then they stumble on a mass grave.They dig it up and without any evidence of a giant he gives up again.Then the younger guy finds the giant's armor while hitting on the older guy's daughter, AND IT'S JUST BURIED UNDER SOME LEAVES!!!!!!!! Oh,it gets worse. They decide to hang the armor on a tree and go to sleep.Guess what happens next?? You just wasted an hour and a half. Watch this movie expecting it to suck and it might not make you angry.If you never see it,you didn't miss anything.

Long dead, or perhaps hibernating conquistador is revived and terrorizes some people in the wilderness.Not really a giant in what we normally think of as a giant the title character is more a really big man. Other than that there isn't much to him as he goes about causing problems for the people in the area where he was buried. You can tell from the lack of real description and enthusiasm how exciting this film is. Its a not a bad film as such but there really isn't much to it at all. Why a giant? beats me, I guess because Conquistador from the Unknown wouldn't have sold as many tickets. The real problem with the film is that this is basically a plug and play film. they took so many stock elements and mixed them together and made this film which is pretty much bereft of any emotion. As 50's horror and scifi films go this is far from the worst, however it is one of the least passionate films. Worth a look if you have nothing else to choose from, but I wouldn't search it out

Though the premise is of course absurd, "Giant from the Unkonwn" is a cut above most B-grade horror films of its era. The difference lies in the cast. Bob Steele, veteran of over 200 films and a familiar face in Westerns, does a very good job as the local sheriff. His gestures, facial expressions and easy mastery of the material give the film its backbone. Morris Ankrum, who plays the inevitable scientist, likewise brought an impressive background to the role. He is probably best known today for his recurring role as a trial judge in Perry Mason, but like Steele he had already been in hundreds of movies when "Giant" was filmed. The supporting cast is good, and manage to approach the silly premise of a giant conquistador on the rampage with a straight face. It's a worthy effort, though it would have been nice to have a better script and a slightly less silly premise.

RATING: *1/2 out of ****Director Cunha's first of four drive-in "horror classics" is merely typical, and not a big deal. It's about a trio of expeditionists unearthing an infamous 6' 6" Spanish Conquistador who promptly picks up his axe and stalks around the woods for a while.Ed Kemmer makes a likeable leading man, and Sally Fraser is the standard helpless heroine. Morris Ankrum seems hesitant to deliver his lines, and the film is sprinkled with enough silly acting to make it endurable for a single viewing.The film falls short with the title character; a helmeted tall man with dirt and mud on his face just doesn't terrify me. It's one of the last makeups done by genius artist Jack Pierce (famous for his timeless Wolf Man and Frankenstein designs for Universal), and not one of his best efforts. The giant does little during the time he's onscreen, and is disappointing.The best film director Cunha made in the genre - and required viewing for any fifties monster fan - is FRANKENSTEIN'S DAUGHTER.
