Julia Roberts, once among America’s most recognizable stars, looked nearly unrecognizable at 44 while filming August: Osage County in Bartlesville, Oklahoma. Famous for her radiant smile and glamorous roles, the Pretty Woman actress underwent a dramatic transformation for the part, appearing makeup-free in modest clothing.

Roberts, who rose to stardom in the 1990 hit, plays Barbara Weston in the 2013 drama. Her character is a woman coping with family turmoil after her alcoholic father goes missing. For the role, she wore loose blue trousers, a cream blouse, and simple styling—far removed from her usual red-carpet image.

During one emotional day of filming, Roberts worked alongside co-star Ewan McGregor. In a tense scene, his character held her hand as they prepared for a sheriff to identify a deceased body at a dock.

Another cast member, best known from Boardwalk Empire, was also spotted on set. She kept her appearance understated, wearing a blue shirt with brown flared pants and her hair pulled into a ponytail.

The film’s ensemble cast was stacked with talent. Meryl Streep played matriarch Violet Weston, while Benedict Cumberbatch appeared as “Little Charles Aiken.” Their performances brought further depth to the adaptation of Tracy Letts’ Pulitzer Prize-winning play.

Casting choices drew headlines during production. Renée Zellweger and Andrea Riseborough were both considered for roles. Riseborough was initially cast as Karen Weston but later withdrew due to scheduling conflicts.

Her departure opened the door for Juliette Lewis, who stepped into the role. Known for her bold performances, Lewis added energy to the already star-studded lineup.

Meanwhile, Abigail Breslin secured the part of Jean Fordham, a role for which Chloë Moretz had also auditioned. With its acclaimed cast and powerful script, the project promised an emotionally charged family drama.
