It was a short run for AMC’s Rubicon, which is being canceled after one season. The political thriller, produced by Warner Horizon Television, premiered on Aug. 1, a year after it was ordered to series, and never found a wide audience, averaging 1.6 million viewers and 439,000 among 18-49 in its first season. It becomes the first AMC original series to get canceled. Here is AMC’s statement: “Rubicon gave us an opportunity to tell a rich and compelling story and we’re very proud of the series. This was not an easy decision, but we are grateful to have had the opportunity to work with such a phenomenally talented and dedicated team.”
