Mother's Instinct

When you read the plot synopsis for the film, you can see why Hathaway was scared of "Mother's Instinct," where she stars alongside Jessica Chastain ("The Eyes of Tammy Faye"). Per the official summary, "Set in the 1960s, 'Mother's Instinct' centers on best friends and neighbors Alice (Chastain) and Celine (Hathaway), who live in a suburban paradise. Both are mothers to two sons of the same age, and their idyllic domestic happiness is shattered after a tragic accident."
In the trailer, that accident involves Celine's son falling to his death from a balcony — a death that Alice tries to prevent but can't. However, after the incident, a major rift grows between the two friends, with Alice starting to suspect that Celine might blame her for what happened ... and that she might want some revenge. "Guilt, suspicion, and paranoia bleed into their friendship," the plot synopsis continues, "as a psychological battle of wills gives way to a darker side of the maternal instinct." Helmed by cinematographer turned director Benoit Delhomme, "Mother's Instinct" has yet to receive a release date, but the thriller will release in the near future.
