10 Star Trek Actors Whose First Appearances You've Totally Forgotten

10. David Warner As St. John Talbot

David Warner has played two iconic Star Trek characters, the ill-fated Chancellor Gorkon in Star Trek VI: The Undiscovered Country and Gul Madred in the classic TNG two-parter Chain of Command. All together now: There are four lights!

What you might have forgotten is that Warner also appeared in Star Trek V: The Final Frontier as the disillusioned Federation representative St. John Talbot. Assigned to the barren Nimbus III with similarly dejected Klingons and Romulans, he falls under the influence of Spock's villainous half-brother Sybok.

In a ruse not a million miles away from The Wrath of Khan, Sybok uses the representatives to lure the Enterprise to the planet for use in his own nefarious plan. Whilst Talbot appears to have a happy ending and a renewed zest for life by the film's end, Warner claims that it was originally a much bigger part. According to the actor, some of his scenes ended up on the cutting room floor, but the novelisation does flesh out the character further.

Accordingly, Talbot made a disastrous mistake during a diplomatic mission and turned to the drink. It's a tragi-comic, minor role for Warner, who would get much juicier Star Trek material in the ensuing years.
