I respect William Shatner a great deal. He's Captain Kirk! That said, he's a fucking asshole.
But even leaving that aside, Shatner will always be Kirk to me - the First Captain. That will never change. And had it been Jeffrey Hunter or Jack Lord, Star Trek wouldn't have been Star Trek. I mean, come on! Hunter didn't even survive to the first movie!
Shatner's still kicking.
I say this now because Shatner's out. We all knew this, of course. There was no way he could be in the new movie - they killed Kirk more than ten years ago. He's dead and gone and we have mourned him but he is kaput, okay? They wanted Shatner in XI, fine, but it was NEVER GONNA HAPPEN. He's gone. He's just... gone.... okay?
And now they're finally calling it. Ten years later and they're telling us the truth. Kirk's Shatner is gone. He will not be coming back. Even Shatner admitted it yesterday. So that's that.
