Sad news: Andy Whitfield, star of Starz's Spartacus: Blood and Sand, officially won't be returning for the series' second season, which was tentatively set to air next September, because he's resuming treatment for a recurrence of cancer. "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," Whitfield said in a statement. No decisions have been made about the future of the series, but Starz still plans to air the prequel to Spartacus: Blood and Sand, Spartacus: Gods of the Arena, this January.
