"Fargo" to return with new cast and crime

FX is taking another trip to "Fargo."

The network announced Monday it has renewed the series for a second season with a new cast, time period and crime. The location, however, is still being worked out.

The earliest the series will air is fall 2015.

FX CEO John Landgraf said at the Television Critics Association summer press tour that while he thinks casting an Oscar-winning actor like Billy Bob Thornton helped attract viewers, he's not sure that it's necessary for season two.

Landgraf noted that Allison Tolman, who began the series as an unknown actress, now has an Emmy nomination.

"We needed Billy Bob Thornton, but now the show, the title, the tone, the writing ... are the star of that show," Landgraf said.

Landgraf compared "Fargo," which also starred Martin Freeman, to HBO's "True Detective," saying the latter "is gonna have to prove that it's more than just a vehicle for movie stars."

Noah Hawley, who wrote every episode of season one, will remain at the helm.

Hawley has "already proven he can write something really great," Landgraf said.

"Fargo," which has earned 18 Emmy nominations, was based on the 1996 Coen brothers' movie starring Thorton, Frances McDormand, Steve Buscemi and William H. Macy.

Also on Monday, FX announced that Louis C.K's "Louie" will return for a fifth season.
