Quintet

A George Lucas directorial effort, THX 1138 presents a stark, minimalist vision of a future drained of emotional expression, which may appeal to those who appreciate Quintet's exploration of a society breaking down and the quest for individuality in a conformist world.

Like Quintet, Zardoz is another science fiction entry from the 1970s that provides a unique and atmospheric experience. The film dives into themes of immortality and societal structure, enveloped in a distinct visual style that lovers of Quintet's dystopian world might appreciate.

This environmentally-themed science fiction film showcases a deep-space botanist tasked with preserving the last remnants of Earth's ecosystems. Similar to Quintet, Silent Running provides a thought-provoking narrative set against the backdrop of a bleak future.
