After a series of showrunner assignments, Zack Estrin is focusing on development this season under his overall deal at ABC Studios. He has sold Canary, a dramatic thriller, to ABC.

Described as “Homeland meets Erin Brockovich,” Canary follows a woman who risks everything to help a whistleblower come forward with secret information that will impact the lives of millions. Estrin will write the script and will executive produce with Nick Hamm and Sabrina Eisenstadt of Momentum, the company behind DirecTV series Rogue and Full Circle.

Former Prison Break co-executive producer Estrin, who worked on the cult Fox drama for its entire run, has served as showrunner on several ABC/ABC Studios series, including The River, Once Upon A Time In Wonderland and, most recently, The Whispers. He is repped by WME.
