King of the Texas Rangers

King of the Texas Rangers is a 1941 American film serial produced by Republic Pictures. Set in the years prior to America entering World War II, the plot is slightly anachronistic in that the serial features a mix of period western and modern elements, which was familiar in the B-Western films also produced by Republic. Although the serial's plot involves cowboys battling Axis agents in Texas, Nazis are never named as such, but their presence is strongly implied within the serial.
