Hollywood actress Leslie Parrish, best known for appearances in Batman, Star Trek and the political thriller The Manchurian Candidate, has died at age 90.

Parrish actually passed away in late 2025, but news of her death was not publicly confirmed until her family revealed it months later.

Erica Berdan, the daughter of Parrish’s second husband, confirmed the actress’ death to The Hollywood Reporter.

Parrish became a familiar face to television and movie audiences during the 1950s, ’60s and ’70s, appearing in some of the era’s most recognizable productions.

She appeared in episodes of the classic 1960s Batman television series and Star Trek, while also landing roles on the big screen.

Her film credits included the 1962 political thriller The Manchurian Candidate, the 1959 musical comedy Li’l Abner, Jerry Lewis’ Three on a Couch in 1966 and the cult 1975 horror movie The Giant Spider Invasion.

But Parrish’s life extended far beyond Hollywood.

The actress became deeply involved in political and social activism, publicly protesting the Vietnam War and founding Speakers and Talent Organized for Peace, an anti-war organization.

She also supported Tom Bradley during his first two campaigns for mayor of Los Angeles and later served on a committee tasked with helping select new municipal commissioners for city departments.

Parrish was married to songwriter Ric Marlow for a little more than five years before later marrying author Richard Bach.

Together, Parrish and Bach became passionate conservationists, making donations that helped protect 168 acres of forest and wildlife habitat.

Parrish once said preserving that land was among the accomplishments she treasured most.

“It’s a dream come true and one of the best things I’ve done in my life,” she said.

She added that protecting the land was something she believed would ultimately outlast her Hollywood career.

“It’s what I’m most proud of,” Parrish said, calling the conservation effort the accomplishment that would “outlast” everything else she had done.

Parrish leaves behind a career that stretched from classic Hollywood movies to two of television’s most enduring franchises — along with a legacy of activism and conservation work that continued long after the cameras stopped rolling.
