HAWAII FIVE-O has added another cast member:
THR has reported that Jean Smart will be playing Hawaii Gov Pat Jameson. Smart is best known as First lady Martha Logan on 24.
Jameson is described as:

A bright, beautiful woman in her early 40s, she’s the Governor of Hawaii, a “local Hawaiian with a Washingtonian’s backgone” who is that rarest of creatures — a completely honest politician. Sincerely sorry to hear of McGarrett’s loss, she offers him the unique opportunity to run a task force imbued with special federal powers beyond the run-of-the-mill police department. Her sincerity impresses McGarrett deeply, and bodes well for their future association.

So Smart joins Scott Cann (Detective Danny “Danno” Williams) Taryn Manning(Mary Ann McGarrett), Alex O’Loughlin (Lt. Commander Steve McGarrett), Grace Parks (Kono Kalakaua) and Daniel Dae Kim(Detective Chin Ho Kelly).
