Michael Clarke Duncan's fiancee says the Oscar nominee for ``The Green Mile'' has died while being hospitalized following a July heart attack.
   
Publicist Joy Fehily released a statement from Clarke's fiancee, the Rev. Omarosa Manigault, saying the 54-year-old actor died Monday morning in a Los Angeles hospital after nearly two months of treatment following the July 13 heart attack.
   
The 6-foot-5, 300 pound Duncan appeared in dozens of films, including such box office hits as ``Armageddon,'' ''Planet of the Apes`` and ''Kung Fu Panda,``...
   
Duncan had a handful of minor roles before ``The Green Mile'' brought him an Academy Award nomination for best supporting actor.
   
The 1999 film, based on the Stephen King novel of the same name, starred Tom Hanks as a corrections officer at a penitentiary in the 1930s.

Duncan played John Coffey, a convicted murderer.
