Perhaps one of the more notorious scenes from Star Wars Episode IV - A New Hope is the scene in the Mos Eisley cantina where Han Solo is confronted by Greedo. This is because of the fact that Han is originally depicted as unequivicably shooting first. I say "originally" because George Lucas started monkeying around with that as he revised the movie in subsequent releases. Here's a video about it:
Well you can all rest easy because I've come to the only conclusion worth talking about that will never be contradicted: Harrison Ford shot first.
He did so in a 1973 episode of Gunsmoke, in fact. See if you don't find it awfully familiar:
It's like Lucas originally borrowed that scene for his own movie frame for frame (in the crucial shooting moment, anyway, as there is a shocking lack of Miss Kitty in Star Wars lore). Maybe I'm far away in terms of how much if at all anyone's talked about this before, but I happened to catch the Gunsmoke episode the other day, and at first it was just a pleasure to see Ford at all, and then to see that play out was even more incredible.
And it's highly unlikely that anyone from Gunsmoke is ever going to edit Hobey's actions any other way.
So if you want to retain the purity of Han Solo's bloody preemptive measures, that's where you should look. I guess it somehow figures, since Han was always a kind of cowboy anyway. And yet Ford didn't play another cowboy until this:
(Which, no matter what they say, is absolutely awesome.)
