Michael Clarke Duncan -- best known for his Oscar-nominated role as a death row inmate who possessed magical healing powers in the 1999 film "The Green Mile" -- died on Monday at the age of 54, according to his fiancee Omarosa Manigault-Stallworth.
Duncan had been in a Los Angeles hospital since July 13 following a heart attack and died on Monday morning after close to two months of treatment.
At 6-feet, 5-inches tall and approximately 300 pounds, Duncan was nominated for an Academy Award and a Golden Globe for his role as gentle giant prisoner John Coffey in "The Green Mile," also starring Tom Hanks. Duncan won the role, in part, due to a recommendation by Bruce Willis, who he worked with on 1998's "Armageddon." Duncan went on to appear with Willis in three more films -- "Breakfast of Champions," "The Whole Nine Yards" and "Sin City."
