But if the alternate ending that McG himself revealed in the press tour for that film came to be, John Connor would have died for sure.
And you thought Terminator: Dark Fate was bleak!
With the ending that was eventually used in director McG’s Terminator Salvation having John Connor (Christian Bale) on death’s door, the canonical ending saw secret Terminator Marcus (Sam Worthington) giving his robot heart so that John could live and lead The Resistance.
But the truly inspired twist would have been that the slain Connor’s likeness would have been grafted onto Marcus’ Terminator body in order to keep humanity’s hopes alive… right before his evil programming kicked in, causing him to kill everyone in The Resistance’s inner circle.
