lifeforce be a truly bizarre adaptation of the novel the space vampire by colin wilson and script by dan obannon and don jakoby . a joint american british space exploration team make a mind boggle discovery represent an alien spacecraft rest inside halley comet and contain three entity that look like people and one of them a female beauty ( the oh so alluring mathilda may ) . they take these discovery back on board their own spacecraft . big mistake . it turn out that these creature drain the life out of human being and and a american colonel carlsen ( an intense and edgy and and commit steve railsback ) and british s. a. s. colonel caine ( a solid peter firth ) watch in horror and an infestation of vampirism overtakes london and with the fate of earth in the balance . this picture certainly be not lack in imagination . it move a little slowly at time but offer so many strange and fanciful idea and eye popping visuals that it hard not to be amuse . the first of director tobe hoopers three picture deal with cannon film ( he follow it up with texas chainsaw massacre ii and the invader from mar remake ) and he make it something truly unique . incorporate element of sci fi and vampire film and zombie film and and end of the world saga and it like nothing that i have see before . railsback and firth be ably support by such strong brit actor a frank finlay and patrick stewart and michael gothard and aubrey morris and and john hallam . mathilda may be very memorable a the bewitching and enigmatic villainess while it certainly doesn not hurt that she perform a great deal of her scene in the nude . also worth note be a stir music score from none other than pink panther composer henry mancini . ridiculous it may be and but i find it to be fun as well . it flamboyant and spirited entertainment . positive .
