the end of the 1960s counterculture

His films like 'One Flew Over the Cuckoo's Nest' (1975) and 'Hair' (1979) directly chronicle the collision between counterculture idealism and institutional reality in the late 1960s and beyond.

'Apocalypse Now' (1979) serves as an epic requiem for 1960s idealism, exploring how counterculture values were corrupted and destroyed in the Vietnam War's chaos.

While working in later decades, his film 'The Fountain' and thematic preoccupations examine the disillusionment and darker undercurrents that emerged as 1960s utopianism collapsed into excess and tragedy.
