the film begin with people on earth discover that their rocket to mar have not be lose but be just drift out in space near out planet . when it retrieve and one of the crew member be ill and one be alive and the other two be miss . what happen to them be tell through a flashback by the survive member . while on mar and the crew be apparently attack by a whole host of very silly bug eye monster . oddly and while the set be pretty good and the monster be among the silly i have see on film . plus and in an odd attempt at realism and the production use a process call cinemagic . unfortunately and this wonderful innovation just make the film look pretty cheap when they be on the surface of mar and the intensity of the redness practically make my eye bleed it be that bad . despite all the cheese and the film do have a somewhat interesting plot as well a a good message about space travel . for lover of the genre and it well worth see . for others and you may just find the whole thing rather silly see for yourself and decide . while by today standard this isn not an especially good sci fi film and compare with the film be make at the time and it stack up pretty well . p when you watch the film and pay careful attention to dr. tremayne . he look like the spit image of dr. quest from the jonny quest cartoon . plus and he sound and act a lot like him and too .
