At the Russell P. Kramer Presidential Library in Ohio, there is a life size cutout of President Kramer in a U.S. Naval officer's uniform. Jack Lemmon really served in the U.S. Navy during World War II.
The scene on the train where James Garner and Jack Lemmon jump to escape the government agents is strikingly similar to Garner's scene in 'The Great Escape' where Garner and 'Donald Pleasance' jump off a moving train to escape pursuing Nazi soldiers. Garner even pushes Lemmon off the train first as he had to do with Pleasance's character who said, "I prefer you just give me good push."
Released four years after The Distinguished Gentleman, another political comedy film which also includes James Garner. While here he was a former president with a philandering nature, in the 1992 film, he was a longtime congressman who died while having sex with his assistant and thus paved the way for Eddie Murphy's character to be elected and assume his post.
The name of the book that former Democrat President Matt Douglas (James Garner) wrote was "The Challenging Years" whilst the names of some of the seven books that former Republican President Russell Kramer (Jack Lemmon had written included "Hail to the Chef !", "Read My Tulips", and "Executive Obedience: Learn from the Master".
To be a "friend of Dorothy" is a phrase which can also translate to being a straight person for gay rights - also known as an "ally." Some allies will also wear the rainbow ring necklace in support of them. President Kramer (Jack Lemmon) might not have known this, but it did save his life from someone he met "over the rainbow."
