Though the series started off with the biggest numbers the Starz network had ever achieved, "Camelot" will not be brought back for a second season.  A rep for Starz cited large production costs a reason for the cancellation.

"Due to significant production challenges, Starz has decided not to exercise the option for subsequent seasons of Camelot with our production partners GK-tv, Octagon Films and Take 5 Productions."

The Irish/Canadian series was a retelling of Arthurian legend in which Arthur is the unknown son of King Uther Pendragon and is raised as a commoner.  After the sudden death of Uther, Merlin tracks down Arthur to place him in his natural place as Uther successor.  This destroys the plans of Morgan, Merlin's half-sister played by Eva Green.  Most importantly, Eva Green shows off her impressive rack several times in the series.
