But when filming alongside Ewan McGregor, the 44-year-old actress was unrecognizable as the actress who rose to fame as Vivian Ward in 1990’s Pretty Woman.

Without makeup and dressed in frumpy clothes, Julia transformed while filming emotional scenes for August: Osage County in Bartsville, Oklahoma.

On set: Actress Julia Roberts and co-star Ewan McGregor were filming their new movie August: Osage County on Thursday.

Hysterical performance: The brunette performed a tearful act

The movie star, who in real life has three children with her husband, cinematographer Daniel Moder, wore a white shirt over a cream blouse and paired it with loose-fitting blue jeans.

Her long brown hair wasn’t glamorously styled to play Barbara Weston, a character from a family that overcomes certain differences when their alcoholic patriarch disappears.

During the intense scene, Ewan held Julia’s hand with great anticipation as they walked toward a boat dock to identify a body for a sheriff.

Mummy look: The Pretty Woman actress looked a little disheveled while filming the intense scene in which they had to identify a corpse for a sheriff.

Upon seeing the body, Julia begins to cry, seeking comfort from Ewan’s character, Bill Fordham, as she continues to cry in his arms.

She may have been hysterically upset during the scene, but moments later, between takes, Julia was dying of laughter.

The actress appeared alongside Julianne Nicholson, who appeared to be pointing something rather amusing to the group.

It’s not her usual look: she wore jeans and multi-layered blouses for the role of Barbara Weston.

The Boardwalk Empire star also looked disheveled, sporting a pair of navy blue slacks, brown bell-bottoms, and her hair tied back in a ponytail.

Other stars of the 2013 film include Benedict Cumberbatch as ‘Little Charles Aiken’ and Meryl Streep and Violet Weston.

The film’s IMBd page states that Renée Zellweger and Andrea Riseborough were considered for the role.

Riseborough was cast, but dropped out due to scheduling conflicts. Juliette Lewis replaced her as Karen Weston.

Chloë Moretz auditioned for the role of Jean Fordham, but lost to Abigail Breslin.
