Cary Elwes is praising the authentic spirits of Rob Reiner and his wife, Michele Singer Reiner, as those who didn't just "talk the talk, they truly walked it."

The British actor, who starred as the charismatic hero Westley in Rob Reiner's 1987 cult classic "The Princess Bride," said in a lengthy Instagram post Dec. 29 that he needed some time to process the deaths of the Reiners.

"This was a man who felt deeply," Elwes, 62, wrote. "Whose heart was filled with love and compassion. He wasn't impressed by how much money you had or if you had a privileged upbringing. He just wanted to know if you were a 'good guy.'"

Elwes also mentioned Michele's talents as a photographer and celebrated the pair's passion.

"To say that they were a great team would be an understatement," he continued. "Their only interest in fame was that it allowed them to shine a light on causes they believed in, especially helping those who were marginalized."
