Ray Romano's brother (Richard A. Romano) and dad appear in the bar scene where Romano is laughing at how Sally turned down the president for a kiss. His dad's the bartender and his brother's sitting next to him.
The scene in which the president walks Sally to her door after their date, was composed of 2 different cameras, one focused on 'Maura Tierny' and the other focused on Gene Hackman, shot 2 months apart. They had to stop shooting cause of weather, but you can see in the shots in that scene focused on Maura it's raining and on Gene, it's not.
When Dr. Sally Mannis (Maura Tierney) is being hounded by reporters for the first time about her involvement with the former American President, and one of them asks, "Have you guys had sex yet?", that guy is actor Jon Manfrellotti, a personal friend of Ray Romano, and a stand-up comedian who used to open for him.
The lines "I don't have cable" when Handy tells his right hand man to stop looking at the two dogs having sex, or "mmmhmm.....yes, i said mmhmmm" uttered by Irma after Handy is brought down to Earth after just having challenged the president to the mayoral race, are a couple of the many ad-libs in the movie added by Ray Romano to his own character and others in the script.
When the president is moving into his house at Mooseport, the movers carry in a painting of Mount Rushmore. There are five faces on the mountain, it appears that the fifth is a likeness of President Monroe Cole (Gene Hackman).
Actress Christine Baranski, playing fictional Former First Lady Charlotte Cole, the ex-wife of former U.S. President Monroe Cole (Gene Hackman), previously portrayed Constance Bulworth, the wife of Senator Jay Billington Bulworth (Warren Beatty), in another political satire, in the political comedy Bulworth (1998).
The picture premiered in a U.S. Presidential election year, the race being between Republican incumbent president George W. Bush and Democratic Party candidate and later Secretary of State Senator John Kerry. The movie debuted stateside in February of that year with the American federal election being held later in November.
The nick-name of Dr. Sally Mannis (Maura Tierney) was "Sal"; the nick-name of plumber Harold Harrison (Ray Romano) was "Handy"; whilst the nick-names of former U.S. American President Monroe Cole (Gene Hackman) were "Eagle", "Eagle Cole", and "The Eagle". The nick-name that Cole had for his former wife Charlotte Cole (Christine Baranski) was "The Wicked Witch of the West Wing".
