Jessica Chastain Says Intense 'Scenes From a Marriage' Strained Longtime Friendship With Oscar Isaac

Chastain said her friendship with Isaac has "never been quite the same" since filming the miniseries together.
The two studied together at Juilliard and have been friends for over 20 years.
Playing a married couple going through divorce affected their real-life relationship.
Chastain said some exchanges on set got under each other's skin and were emotionally draining.
Despite the toll, Chastain believes they just need some time apart and their friendship will recover.
