Cary Elwes Honors Rob Reiner on His Birthday

Elwes also made reference to Reiner's love story with his 'incredibly loving, intelligent' wife who was 'passionate about her family and about lifting others up.'

The Reiners were a 'great team' whose 'only interest in fame was that it allowed them to shine a light on causes they believed in, especially helping those who were marginalized,' according to Elwes.

'In a town where many talk the talk, they truly walked it. Whenever we got together we would talk about family, life, movies and politics. But without fail Rob would always find a way to make us laugh. That was important to him. Finding the joy.'

Elwes sweetly added: 'And if I could make him laugh in return, I felt like I had won the lottery. His laugh was one of the greatest sounds I’ve ever known — so heartfelt it still rings in my ears.'

He thanked the Reiners for 'sharing your life and art with us. Because my heart still aches every time I think of you, I know the grief of losing you too soon will likely never go away. Sure, death cannot stop true love but life is pain without you.'

Elwes concluded: 'With this note my family and I send our deepest condolences and heartfelt prayers to their family, friends and fans.'

Rob's son Nick Reiner, 32, appeared in court last week, where his lawyer entered a plea of not guilty to the murder of his parents two months after they were found stabbed to death in their $13.5 million Brentwood home on December 14.

Last month, it was revealed that Nick's siblings are no longer paying for his criminal defense as he faces murder charges for allegedly killing his parents, which he pleaded not guilty to.

Hours after the killings, he was arrested and has been held without bail.

But as the case moves forward, with prosecutors confirming it is eligible for the death penalty, his legal representation now rests with a court-appointed public defender.
