Long Live The Orgonauts! (1970)

In the distant future, a spaceship inhabited by a group of young descendants of a "subversive" minority who escaped the destruction of the Earth, recovers a capsule in which the hibernating body of a reactionary warmonger has been preserved, who after having caused war and death, it has abandoned the now unlivable Earth. The visual experimentation aimed at the liberation of the gaze is intertwined with psychedelic visions on the one hand and with the orgone theory of Reichian memory on the other.

Unfortunately the movie Long Live The Orgonauts! is not yet available on HBO Max.
