I've heard so much talk about "Firefly" that I went to Best Buy and forked over $40 bucks (SNIP). After watching the first 3 episodes, the jury is still out. I'm still a little shaky on the idea of the western as science fiction.
Actually, Star Trek (the original series) was funded by NBC because Gene Roddenberry sold them on it as a "space western".
Other space western TV series include; Space Rangers (1993, not the 50's Rocky Jones series), Starhunter, Starhunter 2300, ST:TNG, ST:Voyager, ST-DS9, Enterprise, Space: Above And Beyond, etc.
Firefly has to be the best of the bunch. An interesting and believable combination...it was the frontier region of colonized human space after all. It is a shame FOX screwed it up so badly. They only aired 10 of the 13 episodes, and then finally aired the pilot (which introduced the cast and plot) as the last episode? Although my favorite older TV "space western" series is Rocky Jones Space Ranger, followed by Space Patrol and Tom Corbett Space Cadet.
Westerns in general with gun twists? "Yancy Derringer", "Wild Wild West", "Northwest Passage", and even "Daniel Boone".
Spy and PI shows like Danger Man (aka Secret Agent in the USA), Man From Uncle, Honey West, etc had some fun stuff. And what about the guy who was "gun"....Peter Gunn. Loved Combat and Rat Patrol.
And let's not forget the movie "Bullitt"....great sawed-off shotgun scene
So many shows, so many guns.....
