Rob Reiner used his fame to advocate for progressive causes. ‘Just a really special man. A terrible day’

Rob Reiner was known to millions as a TV actor and film director.

But the Brentwood resident, known for the classic films “Stand by Me” and “When Harry Met Sally,” was also a political force, an outspoken supporter of progressive causes and a Democratic Party activist who went beyond the typical role of celebrities who host glitzy fundraisers.

Reiner was deeply involved in issues that he cared about, such as early childhood education and the legalization of gay marriage.

Reiner, 78, and his wife, Michelle Singer Reiner, were found dead inside his home Sunday, sparking an outpouring of grief from those who worked with him on a variety of causes.

Ace Smith — a veteran Democratic strategist to former Vice President Kamala Harris, Gov. Gavin Newsom, former Gov. Jerry Brown and presidential candidate Hillary Clinton — had known Reiner for decades. Reiner, he said, approached politics differently than most celebrities.

“Here’s this unique human being who really did make the leap between entertainment and politics,” Smith said. “And he really spent the time to understand policy, really, in its true depth, and to make a huge impact in California.”

Reiner was a co-founder of the American Foundation for Equal Rights, the organization that successfully led the fight to overturn Proposition 8, the 2008 ballot measure that banned same-sex marriage. He was active in children’s issues through the years, having led the campaign to pass Proposition 10, the California Children and Families Initiative, which created an ambitious program of early childhood development services.

Proposition 10 was considered landmark policy. Reiner enlisted help in that effort from Steven Spielberg, Robin Williams, and his own father, comedy legend Carl Reiner.

“He wanted to make a difference. And he did, and he did profoundly,” Smith said.

Reiner was also a leading backer of Proposition 82, an unsuccessful measure that would have taxed the wealthy to create universal preschool in California.

Former Los Angeles Mayor Antonio Villaraigosa, who had known Reiner since he was a state lawmaker in the 1990s, worked with him on Proposition 10 and was impressed with how Reiner embraced the cause.

“He was a man with a good answer. It wasn’t politics as much as he was always focused on the humanity among us,” Villaraigosa said. ‘When he got behind an issue, he knew everything about it.”

“Just a really special man. A terrible day,” the former mayor said.

Mayor Karen Bass said in a statement that she was “heartbroken” by the day’s events, saying Reiner “always used his gifts in service of others.”

“Rob Reiner’s contributions reverberate throughout American culture and society, and he has improved countless lives through his creative work and advocacy fighting for social and economic justice,” the mayor said.

“I’m holding all who loved Rob and Michele in my heart,” Bass said.

Newsom added, “Rob was a passionate advocate for children and for civil rights — from taking on Big Tobacco, fighting for marriage equality, to serving as a powerful voice in early education. He made California a better place through his good works.”

“Rob will be remembered for his remarkable filmography and for his extraordinary contribution to humanity,” the governor said.
