Lifeforce, also known as "Space Vampires": https://www.imdb.com/title/tt0089489/ https://www.imdb.com/title/tt0089489/ I was blown away by the basic concept - an alien ship (150 miles long!) with only 3 living(?) occupants in a wide elliptical orbit hidden in the coma of Halley's comet so it nears Earth every 75 years whereupon incredibly bad things happen. But also a gorgeous female space vampire (Mathilda May) appears unclothed! And Patrick Stewart is in the film: https://www.youtube.com/watch?v=7uOhTRONUbY https://www.youtube.com/watch?v=7uOhTRONUbY The primary review on IMDB states: https://www.imdb.com/title/tt0089489/reviews?ref_=tt_urv https://www.imdb.com/title/tt0089489/reviews?ref_=tt_urv "...it is quite simply THE most audacious, spectacular, hilarious, absurd, insane, riotous, crazy, deliriously demented science fiction film of all time. I cannot fully articulate why it is deserving of being one spot ahead of Samuel Fuller's "Pickup on South Street" on my list of favorite films, but I do know that it is. "Lifeforce" elevates craziness to an art form. Quite possibly the most entertaining film known to man, and perhaps our greatest achievement as a species."
