Our favorite Vulcan, Spock, recently appeared alongside his modern counterpart, young Spock, Zachary Quinto, in an Audi commercial. Trekkies as ad men, you say? It's not the first time they've boldly gone there.
These are the advertising voyages of the Star Ship Enterprise.
Kirk, Spock, & Chekov appear together watching DirectTV HD on the bridge of the USS Enterprise NCC-1701-A Version 2 in this "Star Trek" DirecTV commercial featuring footage from "Star Trek VI: The Undiscovered Country".
Michael Dorn, who plays the Klingon Worf, appeared on-screen in more "Star Trek" episodes and movies as the same character than anyone else. Dorn is never seen in this ad for T-Gel, but we hear his distinctive voice.
