Avalon (Stargate SG-1)

"Avalon" (Parts 1 and 2) are the Season 9 premiere episodes of the science fiction television series Stargate SG-1. They marked the beginning of a "new" Stargate SG-1 that continued after the ending of the previous season. Despite seeing the departure of Richard Dean Anderson's Jack O'Neill, it sees the introduction of Ben Browder as Lt. Colonel Cameron Mitchell, Beau Bridges as Major General Hank Landry, and Lexa Doig as Dr. Carolyn Lam. They also bring in Claudia Black's character Vala Mal Doran as a recurring character, later to become a regular in Season 10, and introduce entire new storylines including further information about the Ancients, their links to Arthurian legends, and their origins.
