BBC2 has renewed “The Hour,” which airs in the U.S. on BBC America, for a second season of six episodes.

The 1950s-set drama stars Romola Garai, Dominic West and Ben Whishaw and was written by series creator Abi Morgan, who exec produces with Derek Wax for Kudos Film and Television.

“It has been a hugely impactful, much talked about program,” BBC2 controller Janice Hadlow said, “and the potential for plot development is very exciting.”A BBC America spokesman said that although it has not been confirmed whether the cabler would air the second season of “The Hour,” one could “expect to see it on the channel.”

BBC2 said the second season will be set 10 months after the first season ended and will focus on the relationship between news and celebrity in ’50s London.

“‘The Hour’ recommission clearly signals BBC2’s resurgence,” BBC Drama topper Ben Stephenson said, “as it marks the channel’s first original British returning drama series since ‘The Cops.’ A second series really allows the team to build on the characters and their relationships against the exciting backdrop of their workplace.”

Kudos creative director and exec producer Jane Featherstone said: “Taking us even deeper into our characters’ lives and engaging the viewers with its energy, wit and story, we’re chuffed to bits to be able to keep the world alive.”

For BBC2, “The Hour” averaged 2.1 million viewers per episode.

Other BBC2 original dramas set for 2012 include Jed Mercurio’s “Line of Duty,” Stephen Poliakoff’s “Dancing on the Edge,” Paula Milne’s “White Heat” and “Tom Stoppard’s “Parade’s End” (the last of these headed to co-producer HBO) as well as a series of Shakespeare productions.
