SundanceTV has acquired the U.S. rights to the BBC drama “The A-Word” as part of a co-production pact with Keshet International.

The six-episode family drama revolves around a family after their 5-year-old son is diagnosed with autism. “A-Word,” written by Peter Bowker, premieres on the BBC in the spring and will air on SundanceTV later this year. Peter Cattaneo (“The Full Monty”) directed.

“It’s hopeful, honest and ultimately about the power of family, and the range of issues that families can face together, from autism to aging to adultery,” said Joel Stillerman, AMC and SundanceTV’s head of original programming.

The cast includes Max Vento, Lee Ingleby, Morven Christie, Vinette Robinson, Greg McHugh and Chris Eccleston.

“The A-Word” is based on the Israeli Keshet and July August Productions series, “Yellow Peppers,” created and written by Keren Margalit, who is also an exec producer on “A-Word.” The British rendition came through the Endemol Shine-based Fifty Fathoms production banner.

“A-Word” adds to a the busy slate of a half-dozen original dramas bound for SundanceTV this year, starting with the March 2 premiere of period heist vehicle “Hap and Leonard.” SundanceTV is turning Wednesday into its showcase night for original series.
