I've compiled a list of every MK-Ultra movie I know of here:

If someone knows more of them, please reply to this post so I can add them to the list.
A movie I'd definitely consider adding to this list is 'Beyond the Black Rainbow', a film seemingly set in the 80's which tells the story of a girl with strange psychic powers kept isolated in a hellish private facility overseen by strange old doctors/occultists who turn children into robotic slaves, and seem to get some parasitic pleasure out of the psychic connection they establish with her using drugs when she's in extreme discomfort. Very much a nightmare-vision of an MK-Ultra style program, and brimming with symbolism we're all used too as fans of the site; the device which controls and dampens the girls psychic powers, for example, is a large and humming black pyramid.
While not necessarily 'about' MK-Ultra and similar processes, another movie I think VC might want to take a look at is 'Dark Skies', which follows the pretty standard 'paranormal horror' film-formula while using 'Aliens' as its adversary rather than 'ghosties' or 'demons'. What struck me as significant about this movie was its strange focus on pornography and its implied role of inspiring/allowing the interest of the 'aliens' in the young child/eventual victim of abduction to develop. The hand-in-hand nature of the threat of financial fragility for the family and the threat of alien influence is a strange one as well, and there's a scene toward the end- projected into the eventually taken child's brain- of his 'deadbeat' dad engaged in a robotic murder-suicide, having killed the rest of his family with a shotgun and trying, with a mechanical lack of success, to finish the job on himself. The imagery and strange themes of the movie didn't strike me as a remotely typical direction for a 'spooky alien movie' to take, and felt more like the Aliens were just a metaphor for real-world people of power, and their capacity to destroy lives with impunity
On the transhumanist front, I encourage everyone to check out the excellent dystopian science-fiction film 'Advantageous'. This is a drama, no shoot-outs or action scenes for those seeking base entertainment, but the story it tells is horrifying, depicting a dreadfully believable future that doesn't seem so far off at all, in which rampant automation has made work so scarce that even the customer-service jobs are eaten up by smug and discourteous AI, and the value of human life is dwindling into the negligible.
Another dystopian sci-fi flick that's a bit more fun and uplifting that I recommend to any VC fan is 'Snowpiercer', a bizarre but brilliant little film out of Korea about a self-perpetuating train running a global circuit around an otherwise entirely dead world, the last survivors of humanity confined within. A direct metaphor for the inescapable economic paradigm of poverty and plenty that rules our world, dividing us into different classes but capturing every living soul up in its rotation, and how at the very heart of our seemingly infallible, inescapable, unstoppable system forever rests a dark and secret fuel that warrants its complete destruction/derailment: the slavery of children.
