On why Shatner always spoke his lines as Jim Kirk in an ‘interesting’ manner aka “I speak and breathe in pentameter”:
SHATNER: I had worked in Shakespeare for several years. There’d be a speech in which the character expresses himself or what he plans to do or what was done to him. The speech would be meaningful in terms of the character and the plot, but it would take a hunk. I had learned to speak iambic pentameter, and try and do – I’ve forgotten how many lines – on a breath, so that you would say these words trippingly on the tongue and with a rhythm and then come to the operative word and pause a moment, so that there was a little drama there, and then continue on. That’s the way I approach these things.
