Ole Clint Eastwood said a while ago in an interview that he either had to "finish a movie" or "had to make one more movie", "before I ride off into the sunset." Some guys refuse to go out quietly like they prefer to go down swinging/fighting rather than go out crawling on their hands & knees with a whimper. Clint has to be now somewhere around the age of 94-95 like he has got to have one strong constitution for sure!
