LOS ANGELES -- David Palmer is dead and buried, but his family will still be a presence on "24" next season.

In the show's latest round of casting, the FOX thriller has made DB Woodside, who's had a recurring part as Palmer's (Dennis Haysbert, now on CBS' "The Unit") brother, a regular for the forthcoming sixth season. Regina King ("Ray") has also joined the cast, playing his sister.

Woodside's character, Wayne Palmer, will follow in his late brother's footstep by assuming the presidency, taking over from the twitchy and traitorous Charles Logan (Gregory Itzin). King's character, Angela, is a "powerful advocacy lawyer," according to FOX.

How the two new regulars will play into the story of Jack Bauer (Kiefer Sutherland) in the coming season remains to be seen. FOX isn't dropping any details about the season-six plot, although Sutherland has said it will focus at least in part on Jack trying to save his own skin.

Woodside has appeared in the third and fifth seasons of "24." His credits also include "Buffy the Vampire Slayer," "Romeo Must Die" and "Murder One."

The series will be the first live-action TV work for King since she co-starred in the short-lived NBC comedy "Leap of Faith" a few seasons back. She also voices Huey and Riley on Adult Swim's "The Boondocks."

In addition to "Ray," her film credits include "Jerry Maguire," "Legally Blonde 2" and "Enemy of the State."
