August: Osage County, the dark comedy based on the play by Tracy Letts, premiered in Los Angeles on Monday, and the power-house talents behind the film's brilliance walked the red carpet in style.
In the film, the death of a family's patriarch brings his sons and daughters back home to Oklahoma for his funeral. When they return, tensions elevate as they are all reminded of why they left in the first place, namely their overbearing and emotionally dysfunctional mother.
The cast is simply stunning. Meryl Streep, Julia Roberts, Chris Cooper, Ewan McGregor, Margo Martindale, Benedict Cumberbatch, Dermot Mulroney, Juliette Lewis, Abigail Breslin, Sam Shepard and Juliette Lewis, lead this incredible ensemble.
At the red carpet, the stars spoke to ET about what it was like working on a project as respected and exciting as August: Osage County.
"It was just an incredible experience, getting to sit around that table with those actors, and this script and this story and be able to work with them and see them work," said Abigail Breslin, best known for her work in Little Miss Sunshine and Zombieland.
The script, particularly, is held in high regard by everyone in the cast, and often credited with their success as actors.
"The job of the actor is to make that writing come to life," said Ewan McGregor. "And if it's very good writing, as it was in this, it's quite an easy job."
