So what's the deal to this fight?
Because I honestly can't believe that John McClane would see someone like Voldemort and immediately shoot him.
I really think he'd make jokes and sarcasm, and would dare Voldemort to use his wand. I don't think he'd take it seriously.
"What is that? What is that a halloween costume? Jesus is Comic Con in town? Go ahead, cast a spell Gandalf"
And then Voldemort kills him.
