United Kingdom, Dec. 30 -- Cary Elwes "can finally put [his] grief into words" after Rob Reiner's death.

The 63-year-old actor starred as Westley in Rob's 1987 fantasy film The Princess Bride and they remained close until Rob's shocking death earlier this month.

Cary wrote on Instagram: "Enough time has passed that I can finally put my grief into words. I was 24 when I first met Rob Reiner on The Princess Bride. And from that very first meeting I fell in love with him. I was already a fan of his work so meeting him in person was a dream come true. As we began spending more time together I knew this was someone I wanted in my life. I also knew that by casting me as Westley he was giving me the keys to the castle."

Cary went on to praise...
