I saw the 148m UK theatrical version of TGTBTU which was missing:
- the gunsmith shop scene
- all shots and scenes of the Union commander of the POW camp
- most of Tuco’s beating up by Wallace (a BBFC cut of nearly 3m)
- Maria being flung out of a wagon by confederate soldiers (it started with her opening the door to shack I think)
- Angel Eyes’ beating up of Maria reduced to a slap (more BBFC cuts)
I think there were a few other cuts as well. Alex Cox reported that there was a 121m re-release version shown in UK cinemas a few years later but I have never seen that or heard details of any extra cuts.
If I had to cut another 20m out of the film I suppose the obvious snips would be:
- Father Ramirez scene and other stuff in the monestery
- maybe the one of Tuco tracking Blondie via his cigars
- the first scene of Blondie saving Tuco from the noose cutting immediately to the second
- a radical cut might be to eliminate everything between Blondie abandoning Tuco in the desert to Tuco capturing Blondie whilst he is about to shoot Shorty’s rope. You do lose some gunplay but nothing essential to the story.
- it might also be possible to edit out the entire battle sequence cutting from Blondie and Tuco dismounting to them crossing the river.
