Liam Neeson is in talks to star in Felt, a new film about the Watergate scandal and the source known as 'Deep Throat'.
The whistleblower, FBI agent W Mark Felt, supplied Washington Post journalists Bob Woodward and Carl Bernstein with information as they uncovered the truth behind the 1972 break-in at the Democratic National Committee headquarters in Washington, DC and exposed the scandal which led to the resignation of Richard Nixon as US President.
The new film will be directed and produced by Peter Landesman (Concussion, Parkland) from his own script.
Joining Landesman as producers are The Martian director Ridley Scott and the actor Tom Hanks.
Felt is to begin production in March with negotiations currently taking place to fill out the cast.
After decades of speculation about Deep Throat's identity, Felt confirmed he was the source in a Vanity Fair article in 2005. He passed away in 2008, aged 95.

The Watergate scandal was also the subject of the Oscar-winning 1976 Alan J Pakula film All the President's Men. Based on Woodward and Bernstein's book of the same name, it starred Robert Redford and Dustin Hoffman as the journalists and Hal Holbrook as Deep Throat.
