bicep kiss heard round the world.When Oscar Isaac, 44, planted his lips on the left arm of his “Scenes From a Marriage” co-star Jessica Chastain, 46, on the red carpet at the Venice Film Festival in 2021, he appeared to have shed the baggage of their fictional broken marriage.But in a new Vanity Fair profile, Chastain revealed filming the gut-wrenching HBO miniseries took a toll on her longtime friendship with Isaac.“‘Scenes From a Marriage’ was very tough,” Chastain told the outlet in a story published Tuesday. “And I love Oscar, but the reality is, our friendship has never quite been the same.”The Oscar winner‘s relationship with the other Oscar dates back to the turn of the century, when they were classmates at Juilliard.
