This article contains descriptions and biographies of fictional characters appearing in the HBO original television series Deadwood and in 2019's Deadwood: The Movie. Cast Main cast Recurring cast Main characters Seth Bullock Seth Bullock (Timothy Olyphant) leaves Etobicoke, Ontario and becomes a marshal in Montana. Soon he hears stories of gold in Deadwood. Rather than searching for gold, Bullock opens a hardware store with his best friend and longtime business partner, Sol Star. At the camp, he meets Wild Bill Hickok. When Hickok is murdered, Bullock pursues the killer into the Black Hills and captures him, taking him back to Dakota for trial. After his return, he becomes sheriff of Deadwood. Bullock, one of the few honest men in the camp, is soon enlisted to look after a gold claim for Alma Garret, an upper-class woman from the East Coast whose husband was murdered by Al Swearengen's men over the claim. Eventually, the two become sexually involved, despite the fact that Bullock is married to his brother's widow and is the stepfather of their son, his biological nephew. He decides ultimately to end his relationship with Alma when his wife, Martha, and stepson William come to Deadwood. Later he learns Alma is pregnant with his child, but the pregnancy ends in miscarriage after she is married to Whitney Ellsworth. The relationship between Bullock and Martha continues to be rocky in the aftermath of her arrival until they are struck by tragedy, when William is killed by a wild horse. Though William's death is devastating, it brings the two closer together. Martha chooses to stay with him in Deadwood. Bullock's honest character is instinctively repulsed by Swearengen (and vice versa), but the two form an uneasy alliance and slowly seem to develop a fondness for each other. Together they try to defend the camp against outside interests (e.g., the Hearst mining interests, the territorial government, and Alma Garret's in-laws) who have begun to appear in Deadwood when it begins to show the potential for some degree of wealth. Bullock's fiery temper, however, often clouds his judgment, distancing him from those closest to him. He makes a dangerous enemy of George Hearst because of his determination to stand against Hearst's criminal conduct. This puts him in considerable danger, as Hearst does at one point try to create circumstances in which Bullock might be lured into a lethal ambush. In Deadwood: The Movie,
