Ready to say "hello" and then "good-bye" to "Battlestar Galactica"?

The Emmy- and Peabody-winning series will premiere its fourth and final original season on the Sci Fi Channel beginning Friday, April 4 at 10 p.m. ET/PT. First, however, fans can whet their appetite a week earlier with two back-to-back specials about "BSG."

"Battlestar Galactica: Revisted" will be the first up to bat on Friday, March 28 at 10 p.m. The half-hour special will recap the sci-fi action and Cylon-human drama driving the first three seasons of the show with insightful commentary by executive producers Ronald D. Moore and David Eick.

Beginning at 10:30 p.m., "Battlestar Galactica: The Phenomenon" will investigate the show's impact on pop culture. Actor Seth Green, country singer Brad Paisley and "Talk Soup's" Joel McHale are just some of the celebrities who will share their love for the show.

The fourth season opens with the remaining members of the human race still seeking a new place to call home whilst the line that separates human from Cylon rapidly fades. Starbuck's mysterious return from the dead puzzles Galactica's crew, along with her assertions that she can lead them to Earth, where she had visited when she was supposedly deceased. Also this season, four more members of the fleet can't quite reconcile the fact that they've been Cylons the whole time.
