Saber Rider and the Star Sheriffs is a 1987 animated space western following a similar theme as Galaxy Rangers and Bravestarr and Adult Swim's own Trigun. Originally a 1984 anime series known as Star Musketeer Bismarck(星銃士ビスマルクSeijūshi Bisumaruku) created by Studio Pierrot, it achieved moderate success in Japan. The English language rights to the series was purchased by World Events Productions (WEP) in 1986. WEP reorganized and rewrote the series, incorporating both the original episodes and creating 6 new ones before releasing it under the name Saber Rider and the Star Sheriffs.
