In 2008 Holbrook became the oldest man ever nominated for Best Supporting Actor for his role in Into the Wild.
He played Preston Blair in Steven Spielberg’s Lincoln and won an Emmy award for playing Lincoln himself in a 1976 mini-series.
Hal Holbrook died at his home on January 23, but the news of the actor’s death was only confirmed to the New York Times, this week.
His most famous big screen role was likely that of the infamous Deep Throat, the man who gives the evidence against the Nixon Administration to Woodward and Bernstein, in the 1976 film All the President’s Men.
