Nate Corddry, Molly Parker cure 'Maladys'

HBO comedy pilot also stars Sarah Michelle Gellar

The Maladys are coming together.

Nate Corddry and Molly Parker have been tapped to play Sarah Michelle Gellar's siblings in the HBO pilot "The Wonderful Maladys."

The single-camera comedy is set in New York and revolves around the dysfunctional lives of three siblings (Gellar, Corddry, Parker) who lost their parents at a younger age.

Gellar plays Alice Malady. Corddry will play her younger brother Neil, a bookish grad student, and Parker will play Alice's older sister Mary, a therapist.

Alan Taylor will direct the pilot penned by Charles Randolph.

Corddry, who co-starred on "Studio 60 in the Sunset Strip," recurs on Showtime's "United States of Tara" and will be seen in the summer comedy "The Ugly Truth." He is repped by Endeavor and the Group Entertainment.

"Swingtown" and "Deadwood" alumna Parker is with CAA and d/f management.
