Instead of her signature flaming red locks, Chastain wore a light blonde, shoulder-length wig.

She was caught staring at her phone as she walked from her trailer to the set.

While Chastain was decked out and ready to film, Hathaway was seen wearing a button-down white shirt that left the top few buttons undone and a pair of blue jeans.

She added dark sunglasses to protect her eyes, and she wore her dark brown hair in a style similar to Chastain’s.
