ABC's limited series adaptation of Mitchell Zuckoff's nonfiction book "Fall and Rise: The Story of 9/11" has attached "Hurt Locker" writer Mark Boal.

Boal will pen the scripts and serve as executive producer.

"Fall and Rise" chronicles the stories of those who were lost, saved and forever altered by the deadliest acts of terrorism on American soil.

Earlier this month, ABC announced it was developing the adaptation with plans to air it in 2021 for the 20th anniversary of the Sept. 11 terrorist attacks.

Boal previously won the Oscar for Best Original Screenplay for "The Hurt Locker," which also won Best Picture. He was also nominated for writing "Zero Dark Thirty." Most recently, he co-wrote the Netflix drama "Triple Frontier."
