LOS ANGELES -- Fifty years ago, television followed the advice of Horace Greeley and went West. Eleven of the top 20 shows were westerns, including "Gunsmoke," "Wagon Train" and "Have Gun Will Travel."
But small-town marshals eventually gave way to big-city detectives and with the occasional exception -- "Dr. Quinn: Medicine Woman," "Deadwood" -- the genre went the way of the horse-drawn buggy.
That may make AMC's "Hell on Wheels," a gritty new series set just after the Civil War, a gamble. But executives have good reason to feel optimistic.
"Broken Trail," a 2006 miniseries starring Robert Duvall and Thomas Haden Church as conscientious cowboys, remains the most watched show in the network's history, and reruns of "The Rifleman" on Saturday mornings have performed well.
"It was a no-brainer for us to look for a next great western scripted series," said Joel Stillerman, AMC's senior vice president for programming. "It was not a no-brainer to find it."
What they finally landed on is a series worthy of comparison to the network's other dramas: "The Walking Dead," "Breaking Bad" and "Mad Men."
At first glance, "Hell on Wheels" is a typical western featuring Cullen Bohannon, an ex-soldier determined to kill the men who raped and murdered his wife. Possibly standing in his way is a businessman, Doc Durant, who won't let Cullen's mission -- or anything else -- get in the way of his plans to build a transcontinental railroad.
But then things get tricky.
