New York - Starz network says it is ending its highly successful Spartacus saga next season.
In an unusual move announced on Monday, Starz will conclude the action-adventure series while it's still a big hit, and after only three seasons (or four, counting a "prequel" season).
This season the series drew six million viewers, an enormous number for a paid subscription channel.
Creator-executive producer Steven S DeKnight promises a "stunningly epic" final season.
That 10-episode cycle, which will kick off next January, is filming in New Zealand.
The series stars Liam McIntyre as the Thracian slave-turned-revolutionary who's out to topple the Roman Empire.
McIntyre took over the role from Andy Whitfield, who died of cancer in September 2011.
