Recommend me movies with conspiracy vibes about some secret military project or something like that. It can be a thriller or even a comedy. Films that fit this bill that I like are Men in Black series, The Men Who Stare at Goats, Manchurian Candidate and JFK (probably some others but these are off the top of my head). It'd be cool if the movie's plot was set in the 50's or 60's or referencing these times but it's just a bonus, not a must. Or something that gives the vibes of pic related.
