"Fusing black political comedy with elements from Macbeth and Richard III, the original was set at the end of Margaret Thatcher's tenure as prime minister and follows a scheming British politician with his eye on the top job," is what the original was about.
MRC and Fincher's adaptation will change the setting to the U.S. but maintain focus on issues of political ambition and blackmail.
The original series, based on a novel by Michael Dobbs, was honored with an Emmy Award for Outstanding Writing in a Miniseries. Ian Richardson went on to win the BAFTA TV Award for Best Actor for his portrayal of Francis Urquhart, a rising political figure in the House of Parliament.
Sounds interesting... But actually sounds more like Aaron Sorkin material than Eric Roth. Since Roth and Fincher so far are only "producing", let's see who they will attach as a writer.
