"Chicago Hope" alum Lahti has booked a recurring role on the series, playing Doris McGarrett, the thought-to-be-deceased mother of Steve McGarrett.
"The mysterious character of Doris McGarrett is a pivotal one to the mythology of our show," "Hawaii Five-0" executive producer Peter Lenkov said of the casting, "and we are thrilled to have a seasoned and beloved actress such as Christine to portray her. She's a wonderful addition to the H50 family and the fans will certainly enjoy what we have in store for her. Let's just say that the apple doesn't fall far from the tree."
Lahti recently had a recurring role on "Law & Order: Special Victims Unit" as executive A.D.A. Sonya Paxton.
The third season of "Hawaii Five-0" will premiere in the fall.
