Are the gates really big enough to accommodate this many stars? On the heels of Ben Browder's casting, Stargate SG-1 has added to its roster three-time Emmy winner Beau Bridges (who'll replace Richard Dean Anderson as the new head of Stargate Command) and Oscar victor Lou Gossett Jr. (in the recurring role of a Jaffa leader). In addition, Jeff's big bro will cross over for several episodes to sister show Stargate Atlantis, where he'll meet yet another high-profile new hire, The X-Files' Mitch Pileggi, who's been cast as a colonel who cringes whenever anyone mentions The Mountain.
