Robert Redford has signed up to produce a new Watergate documentary - more than 30 years after playing a journalist who exposed the scandal in All The President's Men.

The Hollywood icon will also narrate All The President's Men Revisited, an upcoming two-hour TV special about the infamous political outrage that led to President Richard Nixon's downfall.

Redford tells The New York Times, "I'm confident that it's the right time to take a look at this moment in history to inform the present."

The actor portrayed Bob Woodward - a Washington Post reporter who helped uncover the scandal - alongside Dustin Hoffman as Carl Bernstein in the Oscar-winning 1976 movie All the President's Men.

The new documentary will premiere on the Discovery Channel next year.
