When Tuco and Blondie get put in the POW camp they both comment after seeing' Angel Eyes'.
I watched it twice and having trouble as to when the three met are were know earlier in the film.
I know that Tuco was going to be hanged and 'Angel Eyes was getting on a stage wagon and comment about a gardian angel- but did I miss why all three knew each other.
It's pretty clear that their is an unseen movie before GBU.
Tuco and AE have had criminal meetings before the events of GBU.
Blondie and AE have had the same meetings before GBU.
The movie chronicles the first time Blondie and Tuco meet.
