The film originally ended with the destruction of the world. Test audiences didn't like it, so a happier ending was shot on a soundstage in Burbank.
As a guest on The Chevy Chase Show (1993) on October 4, 1993, Dan Aykroyd tells a story about he and Chase being pursued by a truck full of paratroopers, while on-location in Morocco. Aykroyd had taken a snapshot of the military unit, who then pursued them at high speeds back to their hotel, where they evaded detection by abandoning their Jeep, and hiding inside a van with curtains in the windows. The next day, as a prank, Aykroyd had John Landis tell Chase that he had been arrested, and should expect them to be coming for him next.
In an interview on Today (1952), Dan Aykroyd said that the movie was intended to star Aykroyd and John Belushi.
The Russian phrase Dan Aykroyd says to the Russian Agents is: "Chem men'she znaesh,' tem loocheh," which translates as: "The less you know, the better."
"Ace Tomato Company" is most likely a reference to United Fruit (now Chiquita Banana), a company widely known to have been involved with the C.I.A. in the 1950s. One of the American doldiers is General Miegs. Henry Meiggs, an American business magnate operating in South America, was the uncle of one of the founders of United Fruit.
