Nursing a bad cold I'm watching a film from 1980 called Hangar 18.
Its an interesting flick that reminds me of an extended X-Files episode. It has the hue of Capricorn One as well from 1977.
An even bigger X link is the presence of Darren McGavin, none other than Kolchak, he of the brilliant 1970's TV series that Chris Carter has cited as an inspiration for the X-Files!
I'm enjoying the film and the spacecraft at its dark heart is really impressive to look at. It looks like a huge black throne sat on an upturned black plate.
I know I've seen something similar.
The screw-off lid of alien or sci-fi jar or canister keeps coming into my head!
The Tesseract jar top? No.
