Bill Murray is a Wry FDR in First 'Hyde Park on Hudson' Trailer (Video)

If you had told people years ago that Bill Murray -- of Meatballs, Stripes, Caddy Shack and Ghostbusters fame -- would play perhaps the 20th century's most dynamic president in a non-satirical film, no one would have ever believed you.

'Hyde Park on Hudson': New Stills of Bill Murray as Franklin Roosevelt Hit the Web (Photo)

Fast forward a quarter century and acclaimed dramatic roles in films such as The Royal Tenenbaums, Rushmore and Lost in Translation, and say hello to President Franklin D. Roosevelt, as portrayed by Murray himself.

In the first trailer for Hyde Park on Hudson, Murray smiles, jokes and wisely winks through the high tension 1939 meeting between America's First Couple, the King and Queen of England -- and the president's cousin and maybe-mistress. Based on true events, the film features Olivia  Williams as Eleanor Roosevelt, Samuel West as King George VI, Olivia Colman as Queen Elizabeth and Laura Linney as Margaret Suckley, the cousin, intellectual companion and rumored mistress of the president.

The trailer hits the late 30s opulence of Roosevelt's home on the Hudson River well, as well as the social awkwardness between the royal couple and Roosevelt, who for all his family's money, fashioned himself a man of the people.

The film hits theaters on December 7.
