The Real Me?

I was with Morgan Freeman, who was a hit man. He shot this old bloke outside his house, but not before the old guy had got off a few shots at him, killing our hero, Morgan. The old guy lay injured and I went over to finish him off. His family suddenly appeared, one phoned for an ambulance, a couple of fit blokes chased me. In the melee I dropped my gun and ran into their barn. They chased me round and round whilst I hunted for my gun.
Suddenly I realised they were the good guys and I was a bad guy. In a film everyone would cheer them on, hoping they got me before I found my gun.
Not liking this new role, I gave myself up, spoiling the whole film probably.
