Hal was honoured by President George W Bush in 2003.
The President awarded him a National Humanities Medal for “charming audiences with the wit and wisdom of Mark Twain as Twain’s outlook never fails to give Holbrook a good show to put on”.
Hal was later nominated for an Oscar for his performance in Sean Penn’s 2007 drama Into the Wild.
The star was married three times. In 1984 he married actress Dixie Carter, who died in 2010.
Hal is survived by his children and two step-daughters, two grandchildren and two step-grandchildren.
