It is unknown what caused Sachs' death. "It is with great sadness that we have to announce the sudden and unexpected passing of Robin Sachs," a statement on his website said. "Please join us in raising a glass to Robin — goodbye, dear friend. Thank you for all the laughter and the cookies. We will miss you so very much."
The London-born actor got his start in the 1972 British film Vampire Circus. In 1991, he took on the role Adam Carrington in the Dynasty: The Reunion miniseries when original star Gordon Thomson was unavailable.
Sachs enjoyed steady work in several sci-fi TV series including Babylon 5, Star Trek: Voyager, Torchwood: Miracle Day and Buffy the Vampire Slayer, on which he recurred from 1997-2000. He also played the evil General Sarris in the sci-fi spoof movie Galaxy Quest.
In addition to his voiceover work on animated movies and video games, Sachs most recently guest-starred on NCIS as an MI5 inspector.
