HBO plans an April debut for Treme, a drama series that follows New Orleans residents as they piece their lives, homes and the city's culture back together in Hurricane Katrina's aftermath.
The show takes place three months after the hurricane flooded 80 percent of the city in late August 2005. While fictional, the series is based on actual political, economic and cultural events that followed the devastation.
"As much as possible, we're trying to show fealty to the post-Katrina history," Overmyer said.
He added that residents "have had their lives transformed by the storm and its aftermath, and we want to be careful in our presentation of that."
The series borrows its title from the name of the neighborhood where jazz is said to be born -- Faubourg Tremé.
Treme's first season will have 10 episodes, including an extended 80-minute pilot. HBO has yet to set an exact premiere date.
