I have been watching the Redux and special features yesterday and a few things sprang to mind about footage from the workprint.
I feel at the start as Willard narrates about the walls closing in… Instead of showing Willard at the Kurtz compound from the end of the film this should be the sex scene with the prostitue while Jim Morrison is saying “Fuck Fuck, Yeah” before Willard has his mental breakdown about his wife.
Pretty much everything is ok so far as Redux is concerned but without the French Plantation and some parts at the end.
To me It feels like we should get the Booby trap “floating Baby” scene and the Monkey Sampan scene instead of the plantation scene.
There is also a small part missing for which Lance shoots at a Water buffalo near the Red Banners before the gun fight from the jungle that kills “Clean” (Lawrence Fishburne) The machine gun fire actually gave their position away. Potentially you could have the burial at the french plantation and then carry on up the River.
I think what can be inferred by the workprint is to do with Willards BLack Shirt so possibly Willard may have Killed Colby and Dennis Hopper photo journalist quite quickly and then Kurtz let’s Willard go after a while?
