The make and model of the real life car that Democrat President Franklin D. Roosevelt drove with the special hand controls, was a 1936 Ford Phaeton, and it is on display at the "FDR Presidential Library & Museum" in Hyde Park, New York State, USA.
The gag about the antique anti-U.K. political cartoons is based on truth. These historic cartoons are located in the foyer of Franklin D. Roosevelt's home, King George VI viewed them them upon arriving in the foyer, and made a brief humorous remark to FDR about the cartoons.
On 11th June 1939, the New York Times printed the menus for all of the meals served to the British royals during their visit to Hyde Park. As depicted in this movie, the picnic menu was as follows: Hot dogs, if weather permits; beer and soft drinks; cold ham from various states; turkey, smoked and plain; various salads; doughnuts; ginger bread cookies; coffee; and baked beans & brown bread.
Screenwriter Richard Nelson was inspired to write the screenplay when he chanced upon some posthumously published letters and diaries from Daisy Suckley. Nelson had even met Suckley in 1991, just before her death.
Franklin D. Roosevelt (Bill Murray) shows Daisy (Laura Linney) a stamp of Victoria Falls in what was at the time Southern Rhodesia now on the border of Zambia and Zimbabwe. He tells her they are the highest waterfalls in the world. They are the largest waterfalls, but not the tallest. The tallest are Angel Falls in Venezuela.
Democrat president Franklin D. Roosevelt biographer Geoffrey Ward has said of this film: "It is true that [FDR and Margaret Suckley aka Daisy] drove to a hilltop that they loved at some point in 1935, and that something happened on that hilltop. I think he kissed her, which meant a great deal to both of them. And it started a long, first flirtatious and then very fond friendship. But what happened in the film did not happen."
"Hyde Park on Hudson", not surprisingly, is located alongside the Hudson River, which is located in Dutchess County in New York State, USA and is situated about ninety miles north of New York City in the same American state.
Conrad Black, author of the book "Franklin Delano Roosevelt: Champion of Freedom", said of this film that it took "large . . . sometimes scurrilous, liberties with historical facts." Specifically, Wikipedia states he said "the movie erred in its depiction both of Roosevelt's relationship with women and of Eleanor Roosevelt's sexuality."
Laura Linney also previously played women who were intimate with American commander-in-chief U.S. Presidents, both real and fictional: as President Bill Mitchell (Kevin Kline)'s mistress in Dave (1993) and Abigail Adams in the HBO miniseries John Adams (2008).
Hyde Park's main movie theater is the "Hyde Park Roosevelt Cinemas" and its high-school is the "Franklin Delano Roosevelt High School" which are both named after the town's most famous native son, the late former four-term Democrat President Franklin D. Roosevelt.
Eleanor Roosevelt, the wife of Franklin D. Roosevelt, converted the Val-Kill Cottage into a factory named Val-Kill Industries. This building forms part of the Roosevelt Estate, and is known as Hyde Park on Hudson, but is located away from the main house, the latter which was built in 1826 and is known as "Springwood". Artists and artisans educated and trained people to produce handicrafts. Franklin D. Roosevelt was impressed by the initiative and furthered the concept in his federal stimulus programs. After the factory closed, Mrs. Roosevelt later moved into the cottage, which was furnished with items that had been made there.
The homes of Eleanor Roosevelt, at "Val-Kill" and "Springwood", are both on the U.S. National Register of Historic Places. The Roosevelt Farm Lane Trail, a 3.6-mile round-trip hiking trail, connects Val-Kill and the "Springwood" house.
The National Park Service operates "The Roosevelt Ride", named after the famous Democratic American President Franklin D. Roosevelt, a free shuttle bus ferrying visitors to and from an area train station in Hyde Park on Hudson. The Ride makes stops at the Franklin D. Roosevelt Library and Museum; Val-Kill; Springwood; and FDR's hilltop retreat, "Top Cottage".
Prior to the start of filming this 1930s set movie set in 1939, producer and director Roger Michell immersed himself in research at the "FDR Presidential Library & Museum" in Hyde Park, New York State, USA. Stars Bill Murray and Laura Linney and screenwriter Richard Nelson spent time there as well, and all toured all of the grounds and buildings of "Hyde Park on Hudson".
It was on and around the front porch (aka "The Veranda") of "Top Cottage" at Hyde Park on Hudson that a picnic with King George VI and Amelia Boynton was held in June 1939. The menu included green salad, strawberry shortcake, and hot dogs.
The film, about Democrat American President Franklin D. Roosevelt, was made and released during the presidency of Democrat American President Barack Obama, debuting during approximately half-way through Obama's two four year terms.
Actress Laura Linney, who plays Daisy, would later co-star in another movie relating to the Hudson River, which was Clint Eastwood's Sully (2016) about the "Miracle on the Hudson", the safe crash-landing on the Hudson River by Captain Chesley Sullenberger which saved the lives of all the crew and passengers. Linney in this film play's Sully's wife, Lorraine Sullenberger aka Lorrie Sullenberger.
The film's closing epilogue reads: "FDR [aka Democrat President Franklin D. Roosevelt who is played by Bill Murray] eventually kept his promise and by 1942 Britain and the United States were fighting shoulder to shoulder. When Daisy [aka Margaret Suckley portrayed by Laura Linney] died in her hundredth year, a box of letters and diaries was found under the bed. Her special relationship with the president was, finally, no longer just their secret."
Democrat President Franklin D. Roosevelt is the only ever American President of the United States of America to be re-elected three times, be elected four times, and serves across four presidential terms, though the last was cut short by his passing away in office.
The nick-name of Democrat President Franklin D. Roosevelt was "FDR". Other later Democrat Presidents would also have three-letter acronym nicknames, such as John F. Kennedy - "JFK" and Lyndon Johnson - "LBJ". These two American Presidents were actually the next two Democrat Presidents of the United States of America after "Ike", the pair's presidencies following Republican President Dwight D. Eisenhower, whose nick-name also had three letters. He took office after Democrat Vice President Harry S. Truman's term, the latter who had become President when "FDR" passed-away.
Star Bill Murray previously and most famously starred in Ghostbusters (1984), and its sequel Ghostbusters II (1989), where one of his Dr. Peter Venkman character paranormal investigator colleagues was portrayed by an actor who was last-named "Hudson". This was actor Ernie Hudson who played Winston Zeddmore.
