Just a quick look into his IMDB.com profile will assure you that this man was a true heavyweight in the world of genre projects. He leaves behind a resume of well over two hundred different roles; though some of them were small, there's no discounting his incredible contribution to many of the shows we've grown to love over the years.
Need a few names?
Well, how about the fact that -- as a voice actor -- the man scored his debut bringing to life aboard the original incarnation of Mobile Suit Gundam (1979-1980)?
Go on, you say?
The list is long and illustrious, indeed. Sliders. Highlander. The X-Files. Honey, I Shrunk The Kids: The TV Show. The Net. Viper. Mercy Point. The Sentinel. The Outer Limits. Seven Days. The Immortal. Stargate: SG-1. Jeremiah. Smallville. The Twilight Zone. Touching Evil. The Dead Zone. The 4400. Eureka. Flash Gordon. Masters Of Science Fiction. Watchmen (2009).
And this doesn't even touch on his many voice appearances in animation or as a supporting player offscreen in countless other projects.
Though he's no longer with us, we'll thankfully always have his work to remember him by.
Thoughts and prayers are extended to the fans, family, and friends of Mr. Kopsa.
