John Gallagher Jr., Jesse Plemons, Zoe Kazan are the newest additions to the cast of HBO's upcoming mini-series, Olive Ketteridge.

The series stars Frances McDormand and Richard Jenkins, and is executive-produced by McDormand, Tom Hanks, Gary Goetzman and writer Jane Anderson.

Based on Elizabeth Strout's Pulitzer-winning collection of short stories titled Olive Kitteridge, the series captures the microcosm -- set in a small New England town -- of protagonist Olive's (McDormand) community, family and friends, seen through her eyes. The stories highlight the crimes and illicit affairs, which expose the seedy underbelly that exists beneath the town's staid exterior but are told with a measured degree of wit and humor.

Jenkins plays McDormand's husband and the couple have a son, Christopher (Gallagher). Kazan has signed-on for the role of Denise, a co-worker at Henry's pharmacy, and Plemons will play a delivery boy at the pharmacy named Jerry McCarthy.

The Newsroom's Gallagher is already well-acquainted with the HBO network. He is also starring opposite Brie Larson (the United States of Tara) in the upcoming indie-film Short Term 12, which releases on Aug. 23.

Kazan (Ruby Sparks) also has a movie release, The F-Word, lined-up at the Toronto Film Festival in September that co-stars Daniel Radcliffe co-stars. Plemons is best known for his character as the cold-hearted killer and Heisenberg's temporary side-kick in Breaking Bad.

Lisa Cholodenko (the Kids are Alright, High Art) will be directing the film. The project was initiated by McDormand who read and loved the book even before it won the Pulitzer. The actress paid out of her own pocket to obtain the rights to adapt the book, and approached Anderson to write the script.
