consider that this film be make in 1963 and in czechoslovakia and at a time when so much sci fi schlok be produce in the spacefaring united state and this film be a rare and welcome sight to the eye . intelligently produce and design and with good character development and good special effect and i miss see this film which seem to have be lose in the great transition to video while i know of no distributor for it . it do have it corny moment and but this be excusable in light of the time in which it be make . the end be unfortunately change for u. s. viewer and which be a shame while it be the u. s. end which get criticize most . i imagine the european end would have be more in keep with it originality and and would hope that american international would re release it in the u. s. and with new dub ( i be one of those non purist who can not stand sub title . they interfere with the enjoyment of the image . and yes and dub can be do well and when do right . ) . it be nineteen year since i saw it over the airwave . i hope it have not vanish while it would be a shame for others not to experience it .
