very bad but watchable science fiction film that suffer from abominable special effect and poor acting and and a ridiculous story . the film open with a spaceship return from exploration on mar with a woman and a man with green slime on his arm . she and through some hokey plot contrivance and begin to tell what happen on this fateful trip a almost all the tape seem to be magnetically wipe off . four astronaut take on this journey represent a military type play by gerald mohr and a poor man humphrey bogart who enjoy say the word irish and have the act savvy of a codfish and then there be naura hayden and a beautiful redhead and only female crew member on flight with three men wear the most formfitting suit possible to accentuate all her curve and next and les tremaine and a wonderful character actor from cheap sci fi film like this a the egghead and and last and jack kruschen a sammy the guy from brooklyn with joke and doesn not seem too bright although chosen for his expertise in electronics . none of these performer be really any good and and all of them say their dialog with little conviction . watch tremaine a he utter that scientific nonsense . really and the best out of the four be kruschen and that really say a lot about this film . but bad acting aside and the movie just fall apart when they land on mar via flashback . the angry red planet have a real cheap budget because mar be really the american southwest with a heavy red tint over it . when the story call for something that might look martian and there be drawing place with a heavy red tint over them . you can tell they be drawings the monster be perhaps even bad a we get a bat rat spider with a size upwards of 40 foot that look like some kid get together piece dead animal together . the other significant creature be a giant amoeba with an oscillate eye . whew . these be bad . there be a nice drawing of a martian city and but there just be not enough of this in the film . despite all these big problem and the angry red planet be a fun bad film . it be really fascinating to see how far we have come a a civilization . most of the stuff they use in the movie be so outdated . one guy be use an electric razor with a cord and i think they can get to mar but they be still use cord . director ib melchior give an interesting look to much of the film even with the budgetary constraint and but the story by him and sid pink doesn not fly . and how bout that end with the music and the psychedelic color . groovy man .
