Sci Fi's two-headed franchise of "Stargate SG-1" and "Stargate Atlantis" has landed an Emmy-winning regular, an Oscar-winning recurring star and one of the most familiar faces from recent sci fi television. Beau Bridges, Louis Gossett, Jr. and Mitch Pileggi have signed on for appearances on the two shows, which are both set to begin production in March for summer premieres.

Bridges ("The Fabulous Baker Boys"), winner of a trio of Emmys, will become a regular on "Stargate SG-1," one of Sci Fi's most successful original series as it enters its ninth season. Bridges will play General Hank Landry, the new head of Stargate Command. Bridges' character will also cross over into a few episodes of "Stargate Atlantis."

An Oscar winner for "An Officer and a Gentleman," Gossett will take a recurring role as a Jaffa leader who vies with Teal'c for political control of the new Jaffa nation. That last sentence is bound to be meaningful to fans of the show.

Pileggi, a veteran of FOX's "The X-Files" and The WB's "The Mountain," will appear on "Stargate Atlantis" in the recurring role of a hard-nosed colonel who runs afoul of Dr. Weir (Torri Higginson) and Major Sheppard (Joe Flanigan).
