i buy this movie for a couple of dollar at a clearance warehouse sale one day when just look around . the cover look pretty good and ( in colour ) and but the movie be b and w and ( i wish they wouldn not try to trap u with coloured cover on b and w movie and but it a common thing to look out for . ) . when i watch it i be pleasantly surprise . it turn out to be good than i expect . i be disappoint that it be a b and w and but the effect be pretty good and certainly good than and say and invader from mar which have crappy effect and and it be great to see john banner in something else apart from hogan hero . overall and this movie isn not too bad for a b grade and and certainly worth the two dollar from a nostalgia point of view . it isn not my favourite sci fi and but it not my bad either . it o. k .
