'Brothers & Sisters' confirms new cast

ABC has announced the names of the actors joining Brothers & Sisters for its upcoming flashback episodes.

Fame's Kay Panabaker has been cast as a young Kitty, newcomer Anna Wood has landed the role of Sarah, and Kasey Campbell is reportedly in talks to play Kevin.

The episodes will also feature a younger William and Nora Walker, plus William's former mistress Holly Harper, but these roles are yet to be cast.

Executive producer David Marshall Grant told TV Guide "[The flashbacks] are all in service of understating secrets of the past that are slowly revealing themselves now."

Last week, it was announced that Cody Longo will portray a young Tommy Walker, a role which Joe Jonas was previously rumoured to be up for.
