ABC Family is rounding out its cast for drama pilot Guilt from writers/executive producers Nichole Millard and Kathryn Price (The Game Plan) and executive producer Stephen McPherson.

Billy Zane Zachary Fall 1(Titanic), Daisy HeadDaisy Head 1 (Endeavour), Zachary Fall (Crossing Lines), Katrina Law (Arrow) and Kevin Ryan (Copper) have landed series regular roles on the pilot, a fictional story that draws parallels to the story of Amanda Knox, the American student convicted, acquitted, retried and acquitted again of the gruesome murder of her British roommate in Italy. Guilt is described as an edgy, soapy thriller that revolves around an American in London who becomes the prime suspect in the savage murder of her roommate. As the investigation unfolds, the show will question whether she’s a naive young girl whose poor decisions are being magnified under the ruthless glare of the British tabloids or whether she’s a sociopath who brutally murdered her friend.

Kevin Ryan 2Zane, repped by Undergound, plays Stan Gutterie, an American defense attorney working in London. His law firm banished him to the UK after he ran afoul of one too many judges in the U.S. Head is Grace, an American attending college in London when her Irish flat mate is found brutally murdered at their place. Fall plays Luc, Grace’s boyfriend in London; Law is Olivia, Grace’s older sister; and Ryan, repped by Atlas Artists, Gersh and 42 Management in the UK, plays Patrick, Molly’s older brother.

Guilt is a co-production of Sea to Sky Entertainment – the joint venture between Lionsgate TV and Thunderbird Films – and BV Family Prods in association with ABC Family.
