Watched this english movie as a child on VHS Tape or as we used to call in India then VCR (Video Cassette Recorder/Player) some where in late 1980s. So please pardon some inaccuracies.
Movie has giant spiders or some tentacles alien organism on board a huge space ship that has lift/elevators which the organism uses to travel across floors of the craft.
That’s pretty much all that I remember.
Thanks in advance!
