Josh Grisetti, the Broadway actor celebrated for his work in “Something Rotten!” and a recurring role in the final season of “The Marvelous Mrs. Maisel,” took his own life on July 10 at age 44. The theater community responded with widespread mourning this weekend, as colleagues, students and fellow actors remembered him as an extraordinary performer and dedicated educator.

Grisetti’s death was first announced by his close friend and former co-star Rob McClure, who posted an emotional Instagram tribute on July 12. McClure said he could not yet process the tragedy and expressed sympathy for Grisetti’s wife and family.

Grisetti is survived by his wife of six years, Mackenzie Grisetti.

A Man of a Thousand Faces

Grisetti’s agent, Rick Ferrari, remembered his client as a “tremendous talent” in a statement, praising the range that made him equally at home in comedy and drama. Grisetti was, Ferrari said, “the man of a thousand faces.” Ferrari noted that his client was beloved by his students and said the entire team felt shock and sorrow at the loss.

That devotion to teaching became a defining part of Grisetti’s later career. He led the Musical Theater program at California State University, Fullerton, an institution where faculty and students said he transformed the department. He had previously taught at Fullerton College and Loyola Marymount University, mentoring a new generation of performers even as he continued to work as an actor, director and writer.

McClure honored both aspects of his friend’s career in his tribute, sharing cherished memories of performing together onstage and witnessing Grisetti’s impact on young artists. He mentioned serving as best man at Grisetti’s wedding and described the loss as cataclysmic, ending with “We love you Josh.”

From Broadway to ‘Mrs. Maisel’

Grisetti built a substantial résumé across the New York stage. In “Something Rotten!,” he and McClure starred as Nigel and Nick Bottom in both the Broadway production and national tour of the Renaissance-set musical comedy that showcased Grisetti’s gift for physical comedy and rapid-fire wordplay. In 2015, he appeared on Broadway as Marty Kaufman in “It Shoulda Been You,” a role that connected him with another close friend and collaborator, Sierra Boggess.

On television, Grisetti reached his widest audience through “The Marvelous Mrs. Maisel.” Playing Ralph Emerson in eight episodes during the show’s final season, he became part of the beloved period comedy’s ensemble. Years earlier, he worked with Donal Logue and Sofia Vergara on the short-lived ABC sitcom “The Knights of Prosperity,” which ran for nine episodes before being canceled. His other credits included appearances on “Nurse Jackie” and “The Good Fight.”

An Outpouring From the Theater Community

Boggess posted her own Instagram tribute with multiple photos. She praised Grisetti for bringing light, thought and humor to every space he entered and celebrated his talents as an actor, director and writer, noting that his students benefited greatly from his mentorship. She said the cast of “It Shoulda Been You” remained like family and anticipated a lengthy grieving process.

Many performers responded to McClure’s announcement. Rachel Zegler posted a heart emoji. Stephanie J. Block called Grisetti a kind and beautiful soul and sent comfort to those mourning him. Donna Murphy, a Tony winner, expressed devastation over the loss, praised Grisetti as a gifted artist and person, and offered prayers for his family.

Grisetti’s final Instagram post, dated July 8, offered a poignant glimpse into his last days. He explained that he had withdrawn from directing “Legally Blonde: The Musical” at the Trentino Music Festival due to personal circumstances before opening night. A video showed the cast displaying his photo on a phone screen while calling out, “We love you, Josh!” He wrote that he had cried on the plane and that small gestures went a long way when a heart is hurting, signing off with affection for what he called his group of misfits.

The image of that farewell — colleagues rallying around a director who could not stay to see his work come to life — has resonated painfully with those now mourning him. Across Broadway stages, university classrooms and screens, Grisetti leaves behind a body of work and a circle of students and collaborators shaped by his presence.
