immortality and aging

His films like 'After Life' and 'Still Walking' explore mortality, memory, and the passage of time through intimate family narratives that contemplate what remains after death.

He obsessively examined time, decay, and spiritual transcendence in works like 'Stalker' and 'Mirror,' treating cinema itself as a meditation on mortality and the search for meaning beyond physical existence.

His philosophical filmography, particularly 'The Tree of Life' and 'Song to Song,' poetically grapples with human fragility, cosmic insignificance, and the eternal struggle between temporality and transcendence.
