David Warner in TrekDavid Warner is an accomplished actor, in both the U.S. and U.K., who has portrayed many dramatic characters, especially those in sci-fi/fantasy genres. He memorably appears three times in the Trek franchise - "Star Trek V: The Final Frontier," "Star Trek VI: The Undiscovered Country," and 'Chain of Command, Parts 1 and 2' from "Star Trek: The Next Generation." We look at these three vastly different characters of St. John Talbot, Chancellor Gorkon, and Gul Madred and how Warner developed them in those Trek stories.
