The actress, 39, made a rare appearance in photos alongside her costars and fellow actors at the Williamstown Theatre Festival, where she'll be starring in Jeremy O. Harris' new play,Spirit of the People, at the Massachusetts festival's MainStage Theatre this summer. In a new photo shoot forVogue, Heard — whose spokespersonconfirmed to PEOPLEin May that she recently welcomed twin babies — could be seen smiling alongside her fellow actors and posing for a solo shot while surrounded by nature. The photos were taken by Hunter Abrams and Sam Lee. Pamela Anderson, Whitney Peak,William Jackson Harperand Chris Messina — all of whom are also slated to take part in the festival — were among the cast members and creatives who also posed for the photo shoot. Ernesto Ruscio/Getty Harris, part of the festival's inaugural Creative Collective tasked with curating the programming, described the atmosphere toVogueby quoting Tennessee Williams, who is being celebrated at this year's festival. "In an interview with Jason Grissom, [Williams] once said, 'There's magic in those woods,' in regard to the verdant woods around Williamstown I've found myself in this summer," Harris, 36, said. "He was right: There is a magic to the madness of making theater out here that has infected all of us this summer." "Perhaps it's the giddy 'theatre camp for adults' energy, or just the ways in which so many new theater artists — Katina [Medina Mora, director ofSpirit of the People], Nicholas [Alexander Chavez], Whitney [Peak], Amber [Heard, also ofSpirit of the People], and many more — have thrown themselves headfirst into this world and aren't just keeping up but pacing some of their peers," Harris continued. "I'm in awe of each of the people assembled this summer, and I hope the experience of meeting these gorgeous works of raw, ambitious art will give you something to chew on as we all dive headlong into this precarious moment in American history," he added. The festival's lineup also includesNot About Nightingales,Camino RealandThe Gig: After Moise and the World of Reason.
