Beau Bridges, Lou Gossett Jr. and Mitch Pileggi (“The X-Files”) have joined Sci Fi Channel’s “Stargate” skeins.

Bridges will play Gen. Hank Landry on flagship series “Stargate SG-1″ but will also put in a few crossover appearances on “Stargate Atlantis.” Gossett and Pileggi will have recurring roles as a Jaffa leader on “SG-1″ and as a stubborn colonel on “Atlantis,” respectively.

Production on new seasons of “SG-1″ and “Atlantis” will begin in March, with both slated to premiere in the summer.
