Quaid to play Clinton
The movie will focus on the political relationship that Tony Blair formed with Clinton during his early years as Prime Minister.
Michael Sheen who is currently starring as Brian Clough in the Morgan-penned The Damned United will reprise his role as Blair in the HBO movie.
Julianne Moore and Helen McCrory are also on board to play Hilary Clinton and Cherie Blair respectively.
Morgan, who penned hit movies such as The Queen, Frost/Nixon and The Last King of Scotland, is to make his directorial debut with the upcoming film.
Sheen recently hit out at claims from some critics which say he is an "impressionist".
"It's wrong. I hope people will be able to think about it a bit more and see it's not an impression. I don't do impressions," he told the Guardian.
