The famed actress, who plays a stay-at-home mother with a deep-seated fear of turning into a dog, appeared to be miles away from the flash and glam of Hollywood in her characteristically extravagant costume.

She was spotted filming sequences for the film in Los Angeles on Tuesday, wearing no makeup and brown Birkenstocks to complete her look. She had to express guilt after smacking her co-star Scoot McNairy across the face in the scene, which she did with a look of regret as they stood facing each other holding hands. Cameras were rolling the entire time, capturing every second of the incident.

Furthermore, the striped blouse flowing around her shape and lose slacks stood out from the conventional red-carpet attire typical of an actress of her caliber.

While there was no evidence of anger as she acted out this scene, it was clear that she was nervous as she prepared to give this pivotal moment in the story.
