I can't recall the circumstances under which I saw this in the 70s but I remember being impressed although warning others that it was a bit slow and with murky visuals but a great Pink Floyd score. Memory eh! This moves well with interesting situations and encounters with natives and always looking fantastic, on my Blu-ray anyway. The thing is, where is the Pink Floyd score!? It really is barely noticeable until the end credits and I understand there was some dispute as to how their music had or had not been used and that that is why they called the soundtrack album, Obscured by Clouds and not, The Valley. Film boys got wise though and added that title to their own. Clever. Seen today the film is not only a joy and a stunning picture of New Guinea and its inhabitants but an interesting look in microcosm at the rise and fall of the hippy movement. Surprisingly good dialogue and always brilliant cinematography make this an essential watch - for the adventurous.
