Kevin Spacey and Michael Shannon to Play Richard Nixon and Elvis Presley in Bizarre True Story

On 21 December 1970 Elvis Presley rocked up to the White House to request President Richard Nixon make him an undercover Federal Agent.

The bizarre incident will be the subject of the imaginatively titled new film Elvis & Nixon, which is set to star Michael Shannon as the rock legend and Kevin Spacey as the President according to Deadline.

Director Liza Johnson is taking the helm, working from the script by Cary Elwes and Hanala and Joey Sagal.

A synopsis for Elvis & Nixon was also released, and reads as follows...

"Two men at the height of their powers, conscious they could not stay on top forever, both ripped with fear of the inevitable, sharing one famous private moment in the Oval office. ELVIS & NIXON recounts the morning of December 21st 1970, when the King of Rock 'n' Roll (Shannon) showed up on the White House lawn to request a meeting with the most powerful man in the world, President Richard Nixon (Spacey). He had a very urgent request: to be sworn in as an undercover Federal Agent at large. This intimate moment in the Oval office between two men at the height of their powers has never been told."

Producer Cassian Elwes said of the project: "After the enormous success of The Butler I have a deep affection for films set in the White House as does the public. To work with Shannon and Spacey on this movie at the height of their careers is a dream come true."

Alex Walton of production company Bloom added: "It's almost hard to fathom this story which evolved in the oval office between these two extraordinary men. It's almost too good to be true."

Bloom is currently seeking foreign distributors for the film, which as of yet has no release date.
