Julia, devoid of makeup and clad in unremarkable attire, underwent a transformation while filming poignant scenes for August: Osage County in Bartsville, Oklahoma.

On location: Actress Julia Roberts and her co-star Ewan McGregor were shooting their latest film August: Osage County on Thursday

Emotional performance: The brunette showcased a poignant act

The film star – who in reality has three children with her cinematographer husband Daniel Moder – wore a white shirt over a cream top and paired it with relaxed blue jeans.

Her lengthy brunette hair was not styled in a glamorous manner for her role as Barbara Weston, a character from a family that navigates various differences when their alcoholic father goes missing.

In the gripping scene, Ewan grasped Julia’s hand with considerable anticipation as they made their way to a boat dock to identify a deceased body with the Sheriff.

Mumsy appearance: The Pretty Woman actress appeared somewhat unkempt while filming the intense scene in which they were required to identify a dead body with the Sheriff.

Upon witnessing the lifeless body, Julia then breaks down in tears, seeking solace from Ewan’s character Bill Fordham, as she wept in his embrace.

Although she seemed to be in a state of hysterical distress during the scene, moments later, in between takes, Julia was laughing heartily.

The actress was seen alongside Julianne Nicholson, who seemed to be highlighting something quite amusing to the group.

Not her typical appearance: She donned jeans and layered tops for the role of Barbara Weston.

The Boardwalk Empire actress also opted for a less fashionable style, wearing a blue shirt and brown flared trousers, with her hair styled in a ponytail.

Other notable actors in the 2013 film include Benedict Cumberbatch as ‘Little Charles Aiken’ and Meryl Streep as Violet Weston.

The IMBd page for the film indicates that Renée Zellweger and Andrea Riseborough were both considered for a particular role.

Riseborough was initially cast but withdrew because of scheduling conflicts. Juliette Lewis took over her role as Karen Weston.

Chloë Moretz auditioned for the character of Jean Fordham, but ultimately lost the part to Abigail Breslin.

All an act: The group seemed to find something amusing as they collaborated with Julianna Nicholson.
