Query: Astonishing!

This is Arthur Penn's greatest movie and should have taken its place as an American classic long ago. It drops a narrative bombshell halfway through that comes closer than anything else I've seen to evoking the traumas that America experienced in the 60s. It's wonderful to have it avaliable on video at last, but the luminous cinematography by Ghislain Cloquet deserves to be seen on widescreen DVD (any hope of this, MGM?).
