'Hell on Wheels' Season 3: First look at AMC show's new season - Watch here


"Hell on Wheels" is gearing up for its Season 3 return on AMC and Zap2It has the exclusive first behind-the-scenes look at the western's upcoming season.

In Season 3, Cullen Bohannon ( Anson Mount) leaves behind his quest for vengeance and takes on a leadership role with the Union Pacific, racing across the country to beat Central Pacific Railroad in finishing the transcontinental railroad. Big changes are in store as the power struggle between Cullen and Thomas Durant ( Colm Meaney) has been flipped on its head, with Durant now behind bars.

The new season will find all the characters evaluating their morality as the American landscape shifts greatly around them. As Mount says in the preview, it just might be the best season yet.

Check out the preview above to hear all about Season 3 in the cast and crew's own words.

"Hell on Wheels" premieres with a special two-hour episode on Saturday, Aug. 10 at 9 p.m ET on AMC.
