James Butler "Wild Bill" Hickok (portrayed by Keith Carradine ) is a gunslinger, actor, and former law-man.
Wild Bill arives in Deadwood with travelling companions Charlie Utter and "Calamity" Jane Canary . Newly married, Hickok hopes to make his fortune in the camp and have his wife (who resides in Cincinnati, Ohio) join him upon doing so.
Against his better nature, he spends most of his time in Deadwood gambling in poker, much to Charlie Utter's frustration. Utter wants to see his friend settle into a comfortable, quiet life in Deadwood.
While playing poker, Jack McCall assassinates Hickok.
- The real-life Wild Bill was 39 years old when he was killed.
