Amanda Seyfried has enthusiastically jumped into the world of musical film with Lin-Manuel Miranda’s latest project, “Octet.” The actress revealed that her affinity for Miranda’s work led her to commit to the film without fully understanding the premise. Speaking during a red carpet appearance at the Tiffany & Co. Blue Book Gala on April 16, 2026, Seyfried recalled her initial response to Miranda’s invitation. “I didn’t even know what it was exactly,” she admitted. “I just knew that Lin-Manuel Miranda was making a new project… I was like, ‘I don’t care what it is. I’m in.’”

Set to star as Jessica in “Octet,” Seyfried’s character is a pivotal figure in a narrative centred around modern digital dependencies. The film showcases a unique blend of a cappella performances as it explores themes of connection and redemption in today’s technology-driven world. “Eight internet-obsessed people meet in a church basement and lock their phones in a box,” the film’s synopsis states, hinting at a plot that combines humour and introspection through its vibrant musical numbers.
Seyfried’s passion for singing shines through, with her stating, “I’m a born singer. It’s what I love to do.” Her enthusiasm for the project is palpable, as she expressed how working on “Octet” has already become one of the highlights of her career. “We’re in it right now, and some of the best moments of my life have just happened this week,” she shared with the press.
The film is adapted from an original stage musical composed by Dave Malloy, who has praised Miranda’s work ethic and storytelling capabilities. Malloy said, “I was utterly gobsmacked by [Miranda’s] work on Tick, Tick… Boom! and feel so honoured to have such a beacon of the musical theatre world bring this piece into a new life.” The cast features a remarkable ensemble including Rachel Zegler, Jonathan Groff, and Sheryl Lee Ralph, underscoring the film’s impressive talent pool.
Lin-Manuel Miranda himself expressed his excitement for “Octet,” explaining that he had been captivated by the original production since he attended its premiere in November 2019. “Dave Malloy’s score is versatile and brilliant, and it grows more relevant with each passing year,” he commented, elucidating his commitment to breathe new life into the material.
Since rehearsals commenced, Seyfried has formed close connections with her fellow cast members. She noted the positive camaraderie among the ensemble, stating, “Every single person is wonderful and fun and wants to be there. It’s just like we’re all in the same place, breathing the same air and loving the same music.” The collective enthusiasm for the project has clearly fostered a supportive and joyous working environment.
“Octet” is not Seyfried’s first venture into the musical genre; she is widely recognised for her roles in the “Mamma Mia!” films. Reflecting on her past work, she playfully entertained the possibility of a third installment. “The girls in Octet were like, ‘Can we be in it?’ And I was like, ‘Yeah,’” she recounted, indicating that conversations about a potential project are ongoing, with creative ideas already being floated.
In addition to her forthcoming role in “Octet,” Seyfried has recently garnered critical acclaim for her performance in “The Testament of Ann Lee.” She received a Golden Globe nomination for her portrayal of the titular character, demonstrating her versatility and depth as an actress. Discussing the emotional challenges of her recent role, she highlighted the significance of honouring the grief of those lost, emphasising the need for authenticity in her performances.
As of now, “Octet” does not have an official release date, but the anticipation surrounding the film continues to grow. With a stellar cast and Miranda’s esteemed direction, the musical film is shaping up to be a captivating exploration of contemporary issues through the lens of art and performance. Audiences are likely to be intrigued by how Seyfried and her talented colleagues bring this unique vision to life, reaffirming the power of connection in our increasingly digital world.
