Andy Whitfield, who played the title character in the series, will appear in the prequel briefly, but Lucy Lawless and John Hannah take center stage in this story of the rise of the House of Batiatus and its champions before Spartacus arrives as a captured Thracian slave. With the title still to be determined, the prequel will begin production this summer in New Zealand, and is slated to air on Starz in January 2011.

John Hannah returns as Batiatus, owner of the Ludus, along with his wife Lucretia, played by Lucy Lawless. Other returning actors include Peter Mensah (Doctore), Manu Bennett (Crixus), Antonio Te Maioha (Barca), Nick E. Tarabay (Ashur), Lesley-Ann Brandt (Naevia) – and others. New characters will also be added – most notably the gladiator who was champion of the House of Batiatus before Spartacus or even Crixus – who will help fill in the story about the people and politics in the House of Batiatus and ancient Capua as a whole.

Three Australian actors have joined the cast, including Dustin Clare in the lead role.

Clare ("Underbelly," "Satisfaction") will play Gannicus, the champion gladiator in the House of Batiatus before Spartacus came along.

"Spartacus" star Andy Whitfield, who was sidelined for several months after being diagnosed with cancer, will make a brief appearance in the prequel. He has been cleared by doctors to return to work.

Starz also has cast Jaime Murray ("Dexter) as a Capua social climber and Marisa Ramirez ("General Hospital") as a slave girl.

"Spartacus: Gods of the Arena" will begin production on six episodes next month and will hit the air in January. Season 2 of "Spartacus: Blood and Sand," starring Whitfield, will begin production immediately after "Arena" wraps and air later in 2011 for an undetermined number of episodes.

Andy Whitfield, star of Starz's "Spartacus: Blood and Sand," has been advised by his doctors to immediately resume aggressive treatment for a recurrence of cancer, as a result of which he will not be returning for the series' second season, which was tentatively set to air in September 2011.

"It's with a deep sense of disappointment that I must step aside from such an exceptional project as Spartacus and all the wonderful people involved. It seems that it is time for myself and my family to embark on another extraordinary journey. Thank you sincerely for the support so far," said Whitfield.

"Our hearts and prayers are with Andy and his family during this difficult time," said Starz President and CEO Chris Albrecht. "Andy is not only an incredible actor whose portrayal of Spartacus made an indelible impression on Starz audiences, he is also an amazing human being whose courage, strength, and grace in the face of adversity have inspired all of us."

No decisions have yet been made about the future of the series. "Right now, we just want to extend our concern and support to Andy and his family," said Carmi Zlotnik, Managing Director, Starz Media. "We will address our programming plans at some later date."
