The first attempt to adapt the 1989 comedy into a TV show was in 1990. It was canceled after 12 episodes — and featured then-unknown stars Leonardo Di Caprio, Thora Birch, David Arquette and, in the writer’s room, Joss Whedon. Coming off his success with “Friday Night Lights,” producer Brian Grazer teamed up with Ron Howard in 2010 to try again, this time making it an hourlong drama on NBC. The new formula was significantly more successful, with stars Lauren Graham and Dax Shepard anchoring the acclaimed show for six seasons.
1997 was a busy year for turning sci-fi blends of action and comedy into movies. Based on the 1994 Roland Emmerich spectacle, the series continued to build its universe around the scientists and military personnel who make contact with an extraterrestrial civilization through a wormhole. The show launched a second series, “Stargate: Atlantis,” and made for an exciting second act for post-MacGyver Richard Dean Anderson. Showtime carried “SG-1” for its first five seasons before it jumped to Sci-Fi (now Syfy) for its last five.
