%%How so?* AmbiguouslyGay: Col. Caine and one of the male vampires are implied to be this.

* PillarOfLight: from London's Cathedral (where the Space Girl is located) to the vampire spaceship in orbit. [[spoiler:All the human souls are sucked up through it.]]

* ReallySevenHundredYearsOld: Space Girl may look like a twenty-something woman, but that's only because she can shapeshift. She's actually a nigh-immortal space bat who has been roaming the cosmos devouring countless souls for god knows how long.

* SafeZoneHopeSpot: [[spoiler:The secure location trying to deal with the space vampires and the energy-absorbing zombies has already been invaded by one of said zombies. Who is ''the Prime Minister''. Caine and Carlson barely manage to escape. And it also turns out that the researcher that found out the vampires' weakness has been infected as well, which Caine finds out when he goes see him.]]

* VampiresAreSexGods: Rather overtly literal, as Space Girl is practically a [[HornyDevils succubus]]. She seduces her victims with her otherworldly attraction, then devours their lifeforce in the process of making out with them.

* YourSoulIsMine: The lifeforce that the vampires consume is strongly implied to be the human victims' actual souls.

* AllYourBaseAreBelongToUs: Caine and Carlson discover the hard way that the Prime Minister has become one of the energy-absorbing zombies and escape the "secure location" in which the London quarantine is being controlled JustInTime -- as in, they only need to deal with ''two'' zombies trying to climb into their helicopter rather than a massive horde.

* AliensSpeakingEnglish: Space Girl emerges from the pod speaking perfect English. Caine actually takes the time to wonder how that's possible. It's revealed later that they probed the astronauts' minds when they discovered the vampire spaceship.
* AmbiguouslyGay: Col. Caine and one of the male vampires are implied to be this.
* ArtificialGravity: Uses the surprisingly realistic example of applying constant acceleration to a ship in space, and also shows the crew realistically in zero G after they decelerate to make their rendezvous with Halley's Comet. Of course there's a significant issue with relativity if the ship travels long enough to approach the speed of light, but the movie does not say how long the ''Churchill'' was accelerating at 1 G.

* BigBad: The vampire space-ship. The vampires are just servants or parts of it.

* ArtificialGravity: Uses the surprisingly realistic example of applying constant acceleration to a ship in space, and also shows the crew realistically in zero G after they decelerate to make their rendezvous with Halley's Comet. Of course there's a time limit with applying constant acceleration as one would be traveling at the speed of light after 354 days, but the movie does not say how long the ''Churchill'' was accelerating at 1 G.

''Lifeforce'' (1985), possibly [[BestKnownForTheFanservice better known as the "Naked Space Vampire Movie"]], is--[[WhatDoYouMeanItWasntMadeOnDrugs a very strange film]], directed by Creator/TobeHooper for Creator/TheCannonGroup. It is based on an equally strange sci-fi novel by Creator/ColinWilson.

In 1985, a European Space Shuttle mission to Halley's Comet finds in the comet's tail an abandoned spacecraft with three (apparent) naked humans, two men and a woman, in suspended animation encased in glass pods. Later, after taking the pods aboard, the Shuttle goes out of contact with ground control. A rescue mission finds that all the crew are dead but the three people in the pods are still alive. The three not-really-humans are brought to Earth, whereupon they wake up, blow the hell out of the European Space Research Center, and escape. Meanwhile, the sole survivor of the shuttle's crew, Col. Carlsen (Steve Railsback) has returned to earth in an escape pod with a tale of terror...

And then it gets even weirder. Has to be seen to be believed.

Not to be confused with LifeEnergy, which is a trope. Also not to be confused with [[VideoGame/{{Gradius}} the NES port of Salamander]]. Creator/PatrickStewart, Jean-Luc Picard himself, has a small role.

* AFormYouAreComfortableWith: The space vampires took human form by probing the minds of the astronauts for suitable shapes. The human explorers, presuming they're dealing with HumanAliens, then took their bodies on board and shipped them back to Earth for study. Their real forms are the hibernating bat-like creatures also discovered inside the alien spacecraft, which are only shown in their full glory when the female vampire visits Carlson in his dreams, and when [[spoiler:the second male vampire is killed at the end.]]

* PsychicLink: Between Col. Carlsen, the only survivor from the original space mission (Steve Railsback) and Space Girl.

* CatapultNightmare: While Carlson is asleep, he has a nightmare where he sits up in bed and the space girl visits him. Then he wakes up (for real) and sits upright in bed screaming.

* AmbiguouslyGay: Col. Cain and one of the male vampires are implied to be this.

* TomatoInTheMirror: [[spoiler:Colonel Carlsen]] is a space vampire himself. At least that's what the Space Girl tells him.

* ArtisticLicenseAstronomy: Halley's Comet is depicted as taking up one-sixth of the nighttime horizon. In RealLife the 1985-86 visit of Halley's Comet was one of the worst ever as far as visibility goes, with the comet barely visible even with telescopes.

* AllYourBaseAreBelongToUs: [[spoiler:Caine and Carlson discover the hard way that the Prime Minister has become one of the energy-absorbing zombies and escape the "secure location" in which the London quarantine is being controlled JustInTime -- as in, they only need to deal with ''two'' zombies trying to climb into their helicopter rather than a massive horde]].

* AFormYouAreComfortableWith: The vampires assumed human form by probing the minds of the astronauts for suitable shapes. Their real forms are the hybernating bat-like creatures in their spacecraft, notably seen when the female vampire visits Carlson in his dreams, and when [[spoiler:the second male vampire is killed at the end.]]

* OurVampiresAreDifferent: Turns out that the vampire myth stems from these space "vampires," who visit Earth with Halley's Comet to suck the LifeEnergy from humans. They look like giant bats while hibernating inside their spaceship, but they transform into regular humans to seduce their prey. Also, while a stake can kill them, it has to be made of metal, and stabbed a few inches under instead of through the heart.

* WoodenStake: Played with. The space vampires are vulnerable to iron stakes, and they have to be stabbed a few inches below the heart to actually kill them.

* {{Gorn}}: [[spoiler: Two guys have their internal organs burst out rather bloodily, reforming into the shape of the Space Girl.]]
