(from AMC's press release, May 2014) AMC's original Western drama "Hell on Wheels," will return for an expanded fourth season of 13 episodes on Saturday, August 2 at 9:00 p.m. ET/PT. The new season of the series, which stars Anson Mount, Colm Meaney and Common, will air in two parts with the first 10 episodes running consecutively through Saturday, October 4, before taking a hiatus during the networks annual FearFest programming, and returning for the final three episodes beginning on Saturday, November 8. "Hell On Wheels" shifted to the Saturday night slot last year to partner with the network's already successful Western programming on Saturdays, and delivered an average audience of 3.3 million viewers, live plus 3. Additionally, the series nearly doubled (+97%) the network's Saturday prime average and was +152% higher than the total day average. For season four, the network will once again package the series with favorite Western titles, including the films, "The Horse Whisperer," "Tombstone," and "Jeremiah Johnson," and the network premiere of the mini-series, "Comanche Moon." Season Three of "Hell On Wheels" ended with Cullen Bohannon (Anson Mount) married to a pregnant Naomi and living in the Mormon fort where the Swede (Christopher Heyerdahl) was impersonating church leader, Bishop Dutson; Thomas "Doc" Durant (Colm Meaney) back in control of the Union Pacific Railroad which had successfully expanded westward to Cheyenne; and Elam (Common), gravely injured by a bear while searching for the missing Cullen. As Season Four unfolds, civilization makes its way west with the railroad, bringing with it men who attempt to do with their pens what rougher men did in seasons past with their guns. Conflict between government and big business, ranchers, homesteaders and the railroad will continue to define the drama as all of those interests compete with one another for control of Cheyenne, Wyoming, the "Magic City of the Plains," and the most important railroad hub in the country. The season will also introduce several new characters including John Campbell (Jake Weber, "Medium," "The Following").
