After fans went wild for the video on social media, Chastain responded with a tweet of her own and in an Instagram comment, making sure to promote their new show in the process. Read on to see what the actor had to say about the much-talked-about moment and to see the pair on the red carpet. Scenes from a Marriage is a remake of the 1973 Swedish miniseries from writer and director Ingmar Bergman, which is about a couple whose marriage is falling apart. This project marks the second time Isaac and Chastain have played a married couple. They previously starred together in the 2014 film A Most Violent Year.

In the viral video, they pose with Chastain’s arm resting on Isaac’s shoulder, then he smiles at her before leaning in and either smelling or kissing her arm. Chastain then grabs his face and laughs. Another clip shows Isaac looking adoringly at Chastain as she poses. They were also filmed walking giddily while holding hands.ae0fcc31ae342fd3a1346ebb1f342fcb In response, one Twitter user wrote, “the way we have latched onto that video of oscar isaac smouldering at jessica chastain…as a society we are starved for on screen sexual tension.” Another wrote, “Everyone convinced Oscar Isaac/Jessica Chastain must have something going on just shows we need to bring back romcoms and chemistry test. Stars used to be compatible and put on shows while doing promo!” Someone else added, referencing the top prize at the Venice Film Festival, “interesting choice to award the golden lion to that slow mo getty images clip of oscar isaac kissing jessica chastain’s arm but i respect it.” Another fan commented, “the way oscar isaac looks at jessica chastain i would simply faint.” After the video went viral, Chastain posted her own response. On Monday, Sept. 6, she tweeted a screenshot from the original Addams Family TV show of Gomez kissing wife Morticia’s arm. Isaac voices the character Gomez in the animated Addams Family movies, which may be why he referenced this move on the carpet. Along with the screenshot, Chastain posted a devil emoji and “Sept 12th”—the release date of Scenes from a Marriage. She also commented on their red carpet appearance on Instagram. Writer and actor Mindy Kaling commented on one of Chastain’s posts from her time in Venice, “Why is Oscar Isaac the only person allowed to kiss your inner arm.” Chastain wrote back, “don’t hate lol.” For more celebrity news delivered right to your inbox, sign up for our daily newsletter.
