Anne Hathaway at the beach for ‘Mother’s Instinct’!

While walking down the beach between scenes on the Mother’s Instinct set in Port Monmouth, New Jersey earlier this week, Anne Hathaway shields her eyes from the bright sun.

The 39-year-old actress was spotted filming new scenes with her young co-star; who will presumably play her son in the film.

Anne and the young actor were dressed in brightly colored puffer jackets in between shots.

Here’s a synopsis of the film: It follows best friends and neighbors Alice (Jessica Chastain) and Celine (Hathaway) who live an idyllic traditional lifestyle with manicured lawns, successful husbands; and sons of the same age in the “early ’60s.” After a tragic accident, life’s perfect harmony is shattered. Guilt, suspicion, and paranoia combine to sever their sisterly bond; resulting in a psychological battle of wills as the maternal instinct reveals its darker side.”

Last month, Anne and Jessica were seen filming additional scenes.
