I was probably thinking of the black knight in Holy Grail shouting after Arthur. ;)
After the initial burst of anger, Anakin could get more apologetic and desperate, even if Obi Wan is long gone. (Or yelling in the background over Padme's ship leaving Mustafar?) Hayden's emotional meltdown in Shattered Glass comes to mind.
And don't forget "Don't let this one die a virgin!" from The Virgin Suicides. Shouldn't be too hard to splice "me" in there? I think Hayden's voice can be tweaked to sound a little deeper if need be?
Are you still going to censor or cut away from Anakin's BBQ?
