Julie Andrews and More Mourn the Loss of Christopher Plummer: "He Was a Giant of Stage and Screen"

The actor took to Twitter to remember his longtime friend, writing:

A gentleman whose name is Christopher Plummer died today. He was what I call a friend. What is the definition of a friend? Somebody you know intimately whose every breath and every thought that is so much like yours or can a friend be someone whose life is intertwined near and afar with great gaps of time between meetings? That was the kind of friend Chris Plummer was to me. I think the final picture of our friendship was in a documentary I was making in which I interviewed him at a theatre that we both played at the Statford Ontario Festival. We spent the afternoon laughing and rejoicing in our mutual experiences. That afternoon defined my friendship with Chris. I am so sad to lose him. My best, Bill
