All of this talk about Sisko, and I'm still amazed no one's noticed that an entirely different actor played Kirk during the TOS films. I mean, look at all that extra hair he had!
That was hair?
I thought it was a Tribble that decided to live on top of Kirk's head!
Really, each hairpiece should be uniquely named and listed in the opening credits of each film. Somewhere between Doohan and Nichols.
