HBO's half-hour comedy pilot "Suburban Shootout" has added a pair of co-stars.

According to The Hollywood Reporter, Michael Weaver and Mary Birdsong will take roles in the Barry Sonnenfeld-directed pilot.

"Suburban Shootout" is based on a series from Britain's Five (and which aired on Oxygen in this country). Michelle Ashford ("Boomtown," "John Adams") adapted the pilot, which focuses on Rebecca (Judy Greer), a woman who leaves the city for the suburbs only to find herself caught in a gang war between heavily armed housewives.

Weaver will play Rebecca's husband, the suburb's new police chief.

Birdsong will play a member of one of the gangs.

The "Suburban Shootout" cast also includes Kelly Preston, Kerri Kenney and Rachael Harris.

Weaver most recently co-starred with Harris in ABC's "Notes from the Underbelly." His other credits include "The Mullets" and the features "Club Dread" and "Super Troopers."

Birdsong is best known for her role as Deputy Cherisha Kimball on "Reno 911!" and in its feature film spin-off.
