THE LATEST FEED now has a selection of YouTube Firefly clips. (Woohoo!) I highly recommend taking a look at the opening sequence. It has a very catchy theme song with a distinct western flavor, because, as the narrator explains before each episode, life on the outer fringers has resorted to more rustic technologies.
Anyway, here's the link to the O/S and there's a selection of others that will rotate up in the list of YouTube fare below. Enjoy! :)
"You Can't Take the Sky From Me"
Clips from Firefly (primarily Captain Mal Reynolds) with the music of "Hero"
(It starts a little slow, but give it a minute. Some good Firefly dogfight scenes and lots of swashbuckling action.)
