According to his memoirs Roger Moore was again offered the role of Seymour Goldfarb but turned it down, feeling the joke could go no further. His final female companion had been injured in a car crash on the last day of shooting the original film which was also influential in his refusing the sequel.
Roger Moore later regretted his decision to turn down a role in this film after finding out Frank Sinatra was appearing. In his autobiography, he states of this, "Regrets, I've had a few, but too few to mention..."
Frank Sinatra's cameo was his final acting role in a theatrical film, though he would make one final appearance in the TV movie Young at Heart (1995). All his other appearances from here on would be in documentaries and retrospectives.
As this movie features Frank Sinatra, Dean Martin, 'Sammy Davis Jr' and Shirley MacLaine, this movie is arguably the final ever "Rat Pack" movie (i.e. of the 1960s Rat Pack stars, note Joey Bishop and Peter Lawford are not in this film). For this movie, it was the final cinema theatrical movie for both Martin and Sinatra.
Final of the 1970s-1980s action car stunt comedies for Burt Reynolds. These films included the 'Smokey and the Bandit' and 'Cannonball Run' movie series as well as Stroker Ace (1983) and Hooper (1978).
Roger Moore parodied his James Bond persona in the first The Cannonball Run (1981) movie, driving an Aston Martin and frequently, when on camera, a scene was introduced with James Bondesque music. Though Moore does not return in this sequel (see above trivia item), there are a number of new James Bond connections in this follow-up. This movie features Richard Kiel who had played Jaws in The Spy Who Loved Me (1977) and Moonraker (1979) and Telly Savalas who had played Ernst Stavro Blofeld in On Her Majesty's Secret Service (1969). This movie features a car that can turn itself into a submersible vehicle a la the underwater car from The Spy Who Loved Me (1977) whilst Kiel is often seen brandishing his teeth (real, not metal) in a number of shots. Savalas' character as Hymie Kaplan is seen spinning out of control after Arnold (Kiel) gives him the right hook - similar to the scene where Bond dispatches Sir Hugo Drax out of an airlock in Moonraker (1979).
Hal Needham, on the first film's commentary, talked about how Frank Sinatra showed up very early on the set of this film to get his parts shoot, and then left before the other actors even showed up. If you watch closely during the office scene, Sinatra is never on film with the other actors. A few times his back is shown with the other characters facing him, but this is a double.
The car used by Jackie Chan in this movie is a Mitsubishi Starion, sold in the United States under that name but more commonly known as a Conquest, sold by Dodge, Plymouth and Chrysler dealerships. With only trivial exceptions, the ones sold in domestic dealerships differed from the Starion in name only. Within the last few years, the car Chan used in the movie was salvaged and restored by a member of StarQuestClub, the national owner's club for Starions and Conquests, and is now roadworthy again.
The stretched Chrysler Imperial limousine (stretched by 36 inches) used by 'Burt Reynolds' was converted by ASC (American Sunroof Corporation) outside Detroit, Michigan using the front doors from a 1979-81 Dodge St. Regis sedan. This limousine was used in Reynolds previous film Sharkey's Machine and Stick. Co-star Frank Sinatra had a similar limousine converted by the same coachbuilder - which is still owned by the Sinatra family (which was confirmed by a friend of Frank Sinatra Jr. in 2006).
According to Hal Needham in the first film's commentary, they almost got in trouble with the Bond producers because of Roger Moore's role; being that he, among other things, had a car with gadgets. In this film, Jackie Chan's car has all the gadgets a la James Bond (even more than Chan's car had in the first film); and Chan's partner is Richard Kiel, most famous for his role as James Bond's nemesis "Jaws".
Sinatra made a cameo appearance in this film after listening to Dean Martin and 'Sammy Davis Jr' go on and on about how much fun they had during the first film (this is according to director Hal Needham in the first film's DVD commentary).
