Liam Neeson is to star in "Felt," an upcoming movie set to uncover the story behind The Washington Post’s Deep Throat in the Watergate Scandal.

The Ballymena actor will play the title role Mark Felt, the Federal Bureau of Investigation (FBI) Deputy Director who leaked classified information on Watergate. Felt only revealed his identity in 2005.

The series of articles on the 1972 break-in at the Watergate Hotel, headquarters for the Democratic National Committee, made heroes of reporters Carl Bernstein and Bob Woodward. The investigation led right to the Oval Office and eventually to the resignation of President Richard Nixon and most of his inner circle.

Deadline reports that filming "Felt" will begin in March 2016. The movie will be directed by Peter Landesman, who also wrote the script. It’s believed that Sony will release the movie widely on Christmas Day 2016.

Diane Lane will play Felt’s wife, Audrey, who took on much of the burden of her husband’s role. Jason Bateman will play FBI agent and Felt’s lieutenant Charlie Bates, who discovered his mentor’s role in Watergate and is conflicted about whether to destroy his mentor or protect him.
