Jessica Chastain and James McAvoy star in the his and her film versions of a breakup of a marriage after the death of their infant. Directed by Ned Benson, the two films do not cover exactly the same ground although there are many intersections. The films are a study of grief and how different people and perhaps different sexes handle it differently. Benson eventually made one film of it: THEM.
The supporting cast is excellent and includes: Isabelle Huppert, William Hurt, Viola Davis, Bill Hader, Ciaran Hinds. This is a painful movie but well worth your time for the excellent acting and believable plot. There is real chemistry between the leads and you root for them to find their way back to each other.
