Actor Robert Picardo, who has appeared as International Oversight Committee rep Richard Wooley on previous episodes will officially join the “Atlantis” cast this season as he takes command of the Atlantis expedition. The team of military and civilian explorers use the Ancients-created Stargate to travel to the Pegasus galaxy in order to find other technologies left behind by the Ancients.
In this pivotal season, change is the watchword. Friends are lost and made, while alliances are forged and new alien races are discovered. Wooley’s unique leadership style requires a bit of an adjustment for the team led by Lt. Colonel Sheppard (Joe Flanigan) and including Dr. Rodney McKay (David Hewlett), Teyla (Rachel Luttrell), Ronon (Jason Momoa) and Dr. Jennifer Keller (Jewel Staite).
