Bill Murray is to play President Franklin Roosevelt in historical drama Hyde Park On Hudson.
The film, based on a BBC radio drama by Richard Nelson, tells the story of King George VI and Queen Elizabeth's visit to spend a weekend with Roosevelt in his home in upstate New York, the first time a reigning British monarch had ever set foot on US soil.
Ghostbusters star Bill has officially committed to the project after being pursued for the film's producers for a year, Variety reports.
Van Helsing's Samuel West and Peep Show's Olivia Colman are in talks to take on the task of portraying the royal couple after the Oscar-winning The King's Speech, the Daily Mail reports.
Bertie and Elizabeth's trip to America was the beginning of a special friendship. They made a formal state visit to Washington, but then Roosevelt invited them to an informal gathering at his family home Springwood, in Hyde Park, where they bonded over hot dogs, smoked turkey and soft drinks on the front porch, and enjoyed a picnic together the next day.
The film will also explore Roosevelt's close relationship with his cousin Maragret Suckley, who he called Daisy. Laura Linney is in final negotiations for the role.
The film, directed by Roger Michell and produced by Kevin Loader, will begin filming in the UK in July.
