I'm not familiar with that comic, but I know the movie Lifeforce was actually based on a story called The Space Vampires.

Fucked off that some prick outbid me on an auction for this I was looking foward to watching it again.

They were supposed to be energy vampires - they extracted the lifeforce energy or the soul.

I loved this movie. The last time I posted how much I loved it at another forum I got flamed by the Interview with a Vampire crowd. :(

reminds me, must get round to upgrade my copy to dvd, it's always in the sales

There's a bit of Bava's Planet of the Vampires in this, but it owes more to Curtis Harrington's Queen of Blood. Ultimately, Hooper was trying to cash in on the Alien movies, but it's still fun to watch, and good bits by Frank Finlay and Michael Gothard. I think this was about the last major film for Railsback. Too bad.
