Actor Robert Duvall celebrated his 80th birthday, and his 50 years in the movie game today by becoming one of the names--and hands and feet--immortalized in the courtyard of the Grauman's Chinese Theatre in Hollywood. Duvall left his marks in the wet concrete block in front of a crowd of spectators.

Duvall, born in San Diego, is an army vet who once roomed with Dustin Hoffman while the two studied under legendary acting guru Sanford Meisner. His films include the original "True Grit," "The Godfather," "The French Connection," "Apocalypse Now," "A Civil Action," and "The Apostle."
