The 44-year-old actress and the 42-year-old actor had the internet buzzing after they attended the Venice International Film Festival on Saturday, Sept. 4. While walking the red carpet to promote their new HBO series Scenes From a Marriage, the co-stars held hands and wrapped their arms around each other. Isaac also appeared to kiss Chastain's arm.
But don't jump to conclusions. As Isaac and Chastain's fans know, the two are pals. In real life, Chastain is married to fashion executive Gian Luca Passi de Preposulo and Isaac is wed to director Elvira Lind. But in the modern adaptation of Ingmar Bergman's 1973 Swedish series, the castmates play couple Mira and Jonathan.
"I actually don't care that the Oscar Isaac and Jessica Chastain stuff is a ploy," one social media user tweeted. "They clearly took lessons from the Bradley Cooper and Lady Gaga school of putting on a SHOW for promotional/awards purposes and it's working on me! I'm have a blast over here!"
As another put it, "Jessica Chastain and Oscar Isaac understood the assignment."
Even Chastain appeared to play into the attention by posting a photo of Gomez Addams kissing Morticia Addams' arm and sharing Scenes From a Marriage's Sept. 12 release date.
During a recent interview with Dujour, Isaac praised his co-star.
"She's one of the greats," he said. "She's someone that has always inspired me and brought the best out of me, both as an actor and a person. Acting with her is effortless. Nothing needs to be planned in advance. As long as I'm present, I know anything can happen because there is total trust."
And of course, Chastain did the same. "Because Oscar and I are so comfortable, we didn't have to be polite," she added. "In some sense, we could read each other's minds."
