Veteran Stargate SG-1 actors Michael Shanks and Brent Stait are moving to Smallville. The actors will guest star as members of the Justice Society in an upcoming episode.
Stait will play Dr. Fate in the episode. He played Louis Ferretti in the first season of Stargate SG-1 (including “Children of the Gods”). On Atlantis, he pinch-hit for Connor Trinneer and played the Wraith Michael under prosthetics in the second season finale, “Allies.”
UPDATE 2: Writer Geoff Johns confirmed that the episode will, in fact, be a two-parter, with the second half titled “Legends.” (via Krypton Site)
“Society” and “Legends” are expected to air in January. Look for Smallville Friday nights on The CW!
