and half star out of lifeforce be one of the strange film i have ever see and so ridiculous and yet at the time it strangely compel and never the least bit dull . whether it due to the nonstop nudity and the large amount of violence and action and it all come together to make an entertaining 2 hour of cinema . the spaceshuttle churchill have be send to investigate halley comet when they detect something hiding inside the coma of the giant rock . a small team and lead by colonel carlsen ( steve railsback ) and have be send to search the area . what they discover include hundred of frozen bat like creature and three nude and seemingly unconscious humanoid being inside strange crystalline container and two male and one female ( mathilda may ) . they decide to take all three back with them and which result in a catastrophe . when london receive no response from the crew and another crew be send to find out what go on . when they dock with the churchill and they find the remains of the crew and all dessicated beyond recognition . the humanoid be still in perfect condition and and they take them back to london . after various test and the scientist still do not know what these being really be . then and late one night and a security guard in the compound feel compel to enter the room the female be be hold . he touch her shoulder and and she awaken and stand up and and smile at him in a seductive and wicked manner . she approach him and and begin to kiss him and when it become clear that she actually take his lifeforce and suck him of all of his energy ( the effect be slightly cheesy ) . she escape from the compound and begin to leave a trail behind . another man and colonel caine ( peter firth ) and be bring in to track her down . then the men discover that there be a pattern to the lifeforce process . the corpse of the security guard awaken in 2 hour and and take the lifeforce of a doctor . it seem in every 2 hour and this process be repeat by a victim . with the help of the churchill sole survivor and carlsen and they attempt to track the girl down before it too late . lifeforce be pretty good late night entertainment . it have all the element one could look for in such a movie and load of nudity and blood or gore and and plenty of special effect . this be certainly good than a similarly plot film and specie and thanks in large part to a more riveting finale . the performance range from decent to terrible . fare the bad be easily steve railsback and who overact to no end . much good be peter firth and who come through and convincingly and and the gorgeous mathilda may ( she as beautiful a french actress sophie marceau and emmanuelle seigner ) . may do go through virtually the whole role without wear clothing and and there be report that it be hard on her while film and so the fact that she be able to go through every scene without fidget and look uncomfortable be impressive . there be time when she can be quite creepy and be simply seductive . most of the film manage to work because of her .
