I grew up watching Battlestar Galactica. It was one of the many gems put together by Glen A. Larson whose resume included Buck Rogers in the 25th Century, The Fall Guy, Knight Rider, Quincy M.E. and B.J. and the Bear. There was something about Battlestar Galactica, though, that distinguished itself from Larson's other series. Battlestar Galactica, while still being your basic action-based sci-fi show, actually asked a number of deep questions. Where did humanity come from? Where are they going? What does it mean to be human?
One of the key components of Battlestar Galactica was the acting of Richard Hatch (not to be confused with that guy who won the first season of Survivor). When sharing a scene with the legendary Lorne Greene, Hatch evoked a humble optimism that paired so well with Greene's intimidating presence. Once Battlestar Galactica was cancelled, Hatch went on to try to revive the series in the 1990s, going so far as to mortgage his house in order to finance a trailer outlining his vision.
Universal Studios, who held the rights to Battlestar Galactica, were not interested in a continuation, opting instead to reboot the series with Ronald D. Moore at the helm. Hatch was bitterly disappointed and became overly critical of the new series (which, IMO, was actually a great show for the first two seasons). Despite this, Hatch invited Moore to appear at Galacticon, a Battlestar Galactica 25th anniversary convention hosted by Hatch. Moore endured tough questioning from hostile fans of the original series, but his grace under pressure earned Hatch's respect. Moore then offered Hatch a recurring role on the new series as Tom Zarek, a terrorist turned politician. So, instead of remaining indignant over his own vision not being made, Hatch decided to contribute his talent's so someone else's vision, which made the show better than it would have been without him.
Most recently, Hatch had starred as Klingon Supreme Commander Kharn the Undying in the Star Trek fan-film Prelude To Anaxar.
Rest in Peace, Mr. Hatch. You may be Tom Zarek to a generation of millenials, but you'll always be Captain Apollo, leader of Blue Squadron to me. So say we all.
