EXCLUSIVE: Frank Langella, so memorable as Richard Nixon in the stage and screen versions of Frost/Nixon, is back in political mode, and this time he’s playing the guy behind The Guy. He’s joining the cast of the Scott Free/Participant Media/Headline Pictures-produced Reykjavik. The Mike Newell-directed drama tells the story of the 1986 peace summit between Reagan and Gorbachev in Reykjavik, Iceland. Michael Douglas and Christoph Waltz play Ronald Reagan and Mikhail Gorbachev, and Langella will play Paul Nitze, U.S. Secretary of the Navy and Reagan’s most senior and trusted adviser. Langella is coming off raves for Robot & Frank, and he next stars in the Stephen Frears-directed Muhammad Ali’s Greatest Fight for HBO in 2014. Langella recently wrapped Grace Of Monaco opposite Nicole Kidman for director Olivier Dahan, and the indie Parts Per Billion opposite Gena Rowlands and Rosario Dawson. Langella was also Tony nominated for last last stage turn, Man And Boy, and he released his memoirs Dropped Names. He’s repped by ICM Partners.
