The Vikings star came up with the concept for the series, which will focus on various historical figures, and he has written the script for the first episode. Fimmel will also serve as an executive producer.

The first season will centre on American frontier lawman Earp and the time he spent with other western figures Doc Holliday and Bat Masterson. It will also feature the infamous gunfight at the OK Corral in Tombstone, Arizona.

"I've always been fascinated with what motivates people's transgressions and the scandalous journey into infamy," Fimmel says. "I wanted to re-examine stories people think they know without the rose-coloured glasses of Hollywood and let the audience decide for themselves if people like Wyatt Earp were sinners or victims of life circumstances."
