Here is a sampling of the outpouring of love and memories from those affected by Duncan's death:

"I am terribly saddened at the loss of Big Mike. He was the treasure we all discovered on the set of 'The Green Mile.' He was magic. He was a big love of man and his passing leaves us stunned." - Tom Hanks.

"I'm devastated at the loss of Michael Clarke Duncan, one of the finest people I've ever had the privilege to work with or know. Michael was the gentlest of souls - an exemplar of decency, integrity, and kindness. The sadness I feel is inexpressible." -Frank Darabont, director of "The Green Mile."

"He was an interesting actor and he made you forget about that [his size]. He made you think the character looked like a big man rather than it was a big man trying to play the character." - Film critic Jeffrey Lyons.

The Green Mile is among my top favorite motion pictures to the point of owning the DVD. I am saddened by his passing. Sounds like his part as John Coffey, the gentle giant, wasn't really acting -- just a good, kind, compassionate person he was off set as he was on.

I am sooooo sad at the untimely passing of Micheal Clarke Duncan. What a fine actor, he got my attention with his extraordinary role in The Green Mile where he starred along side Tom Hanks, one of my all time favorite movies. To his fiancee' Omarosa my heart goes out to you, and all I want to say to you is......You loved him, we (his fans) loved him, BUT God loved him best! I will keep you and your family in my prayers........Rest in Peace Mr. Duncan you WILL be missed:)
