However, while filming with Ewan McGregor, the 44-year-old actress appeared unrecognizable compared to the iconic Vivian Ward she portrayed in the 1990 film Pretty Woman.
Without makeup and dressed in unflattering attire, Julia was completely transformed as she shot poignant scenes for August: Osage County in Batesville, Oklahoma.
On set: Julia Roberts and her co-star Ewan McGregor were busy filming their latest project, August: Osage County, on Thursday.
Hysterical performance: The brunette actress delivered a moving and tearful performance.
In real life, the screen star, who shares three children with her husband, cinematographer Daniel Moder, wore a white shirt layered over a cream top, paired with loose-fitting blue jeans.
Her long brunette hair was not styled glamorously for her role as Barbara Weston, a character in a family that navigates their differences when their alcoholic father goes missing.
During a particularly intense scene, Ewan held Julia’s hand with great anticipation as they approached a boat dock to identify a deceased body with the Sheriff.
Mumsy appearance: The Pretty Woman actress looked quite plain as she filmed the gripping scene where they had to identify a corpse with the Sheriff.
Upon discovering the dead body, Julia broke down in tears, seeking comfort from Ewan’s character, Bill Fordham, as she continued to weep in his embrace.
Despite her emotional turmoil during the scene, moments later, between takes, Julia was seen laughing heartily.
The actress was joined by Julianne Nicholson, who seemed to be sharing something amusing with the group.
Not her usual look: She donned jeans and layered tops for her role as Barbara Weston.
The Boardwalk Empire star also opted for a dowdy look, wearing a blue shirt and brown flared trousers, with her hair pulled back into a ponytail.
Other notable cast members in the 2013 film include Benedict Cumberbatch as ‘Little Charles Aiken’ and Meryl Streep as Violet Weston.
All a performance: The group seemed to discover something rather amusing while collaborating with Julianna Nicholson
