on a desolate planet and two faction be at war with each other and but there be another menace out there tunnel beneath the ground . an autonomous mobile sword and or screamer and be an incredibly quick weapon name for it high pitch shrieking and and which cut it victim into piece . it turn out and these weapon seem to be evolve on their own and and become capable of take on new form . base on a philip k. dick novel ( his work have also inspire the film blade runner and total recall ) and this be good than your run of the mill and film in canada b movie . slowly and deliberately pace and dialog heavy and subtle and and atmospheric and it reward for those who stick with it . it look quite impressive special effect be excellent and rarely ever get overtly cheesy and the indoor or outdoor set and location work be phenomenal . the snowy and windswept landscape be photograph quite well . overall and it quite a nice film to look at . co script by dan obannon of alien fame and that give it some extra punch and a he always tend to do quite well in the realm of science fiction . the acting be good peter weller be a stalwart and and refreshingly and not one note and hero and and be support capably by roy dupuis ( the rocket ) and andy lauer and and the lovely jennifer rubin ( a nightmare on elm street 3 represent dream warrior and bad dream ) . some of the character be abrasive and although that thankfully never become too much of a distraction . the story twist be actually not one that really surprise me and but i appreciate the story tell in general . screamer be a nice little surprise and worth look into for science fiction buff who have yet to see it . it bleak and chilly and interesting and and reasonably entertaining stuff . i recommend it . positive .
