As a fan of Fred Olen Ray films i have to say prison ship is quite entertaining.i know it has a shoestring budget.John Carridine in one of his next to last films as a space magistrate who sends a beautiful sexy fiery blonde babe(Sandy Brooke)to a prison ship full of babes.run by a busty tough warden played by Marya Gant,and her sadistic one eyed trustee played by Dawn Wildsmith(a olen ray regular)of course there's a twisted sadistic lunatic(Ross Hagen)who wants revenge.because he lost his hand in a fight with the heroine.also on hand is Johnny Legend as a space rabbi,the great Aldo Ray as the a master of torture,and cameo by the beautiful Bobbie Bresee.there's aliens robots,Jagger rats(don't ask)and a space battle lifted from Roger Cormans;battle beyond the stars.and a good opening score that sounds like raiders of the lost ark.granted i saw this movie on ancient VHS so the picture quality is not very good.some critics will think I'm crazy for liking this and giving it 7 out of 10,but remember the critics Siskell and Ebert admitting they enjoyed;invasion of the bee girls and infra man.I'm hoping to see prison ship on a good quality DVD.prison ship is a killer-b movie,i found it enjoyable.
