When Otto leaves Archie's home, he says to Archie's wife Wendy that they would all speak German without the USA. He leaves the house while singing the first verse of the anthem: "Deutschland über alles". The German dubbed version has an altered dialog, he says that they'd all eat sauerkraut and listen to military marches, then he imitates some military marches instead of singing the anthem, as the first verse is considered too nationalist and generally not sung in public.

The scene where Otto sits up in the background behind Wanda (Jamie Lee Curtis) is reminiscent of a scene in Halloween, in which the character of Michael Myers sat up behind Curtis' character.

Michael Palin went on to found the London Centre for Stammering Children after a group of stutterers confronted him regarding the sensitivity with which he dealt with Ken's handicap in this film.

For the French dubbed version when Wanda states that Otto mistook the Gettysburg Address for Lincoln's residence, it is replaced with Wanda stating that Otto mistook General Motors for a hero of the war of '14.

Holds record of Longest Time to Reach #1 as of 2009. The movie was released on 15 July 1988 in the U.S., and reached #1 on 16 September 1988.

The principal interior setting was the flat of Nicholas Lacey and playwright wife Juliet Aykroyd, in a loft development in a former warehouse at Reeds Wharf, Docklands, London.

In the robbery scene, it really was Kevin Kline who shot the crossbow at the sensor. Kevin got the shot off correctly on the second take.

The British Airways plane that can be seen at the airport is a Boeing 747-236 called "City of Manchester", registration G-BDXC. It was sold to European Skybus Ltd & scrapped in 2002 after about 25 years of service.

Jamie Lee Curtis was listed as "Jamie Lee Schwartz" on all the call sheets, because John Cleese found it amusing that her father Tony Curtis's real name was Bernard Schwartz.

In 1989, when this film was shown in the theaters in Denmark, a Danish man named Ole Bentzen, a Danish audiologist, literally laughed himself to death during the scene where Ken gets the chips up his nose. Bentzen's heart rate went between 250-500 beats per minute and he eventually succumbed to cardiac arrest. The story behind this is that the man had made a joke a few years earlier with his family during dinner, where he put a piece of cauliflower up his and every family members nose as a joke and made a bet with them on who could eat up their carrots without the cauliflower falling out. When the scene with Ken and the chips came up, he started thinking about this dinner-incident and laughed so hard that his heart stopped. This story is well known in Scandinavia and spread around as almost an "urban legend" shortly after it happened. It was confirmed by his son, who also told the dinner-story as an explanation to why his father laughed so hard during the chips-scene that he died.

In the opening sequence that introduces the principal cast, a model of the Eiffel Tower can be seen over Michael Palin's shoulder. This may be a reference to Charles Crichton's earlier film The Lavender Hill Mob, in which Alec Guinness tries to smuggle the stolen gold out of England by melting the gold down and disguising the stolen gold as a model of the Eiffel Tower.

John Cleese has said in interviews that Patricia Hayes was the only cast member not to have any material deleted during editing.

Director Charles Crichton's last film.

One of Otto's lines throughout the movie is "Don't call me stupid." In The Ladykillers, One Round didn't like to be called stupid either. Director Charles Crichton was a veteran of the Ealing films, most famously directing _The Lavender Hill Mob_ (1951).

Wanda kisses all of the major male characters at some point.

During the love scene, when Wanda opens up her blouse, Otto says in broken Italian "Ecco le due cupole del catedrale di Milano!" which translates "There are the two domes of the Milan cathedral." Milan's cathedral, actually, has no domes at all.

John Cleese chose the name Archie Leach, Cary Grant's real name, because he was born 20 miles away from where Grant was born (Hughenden Road, Horfield, Bristol), and because it was the closest Cleese could get to being Grant.

The hymn that the choirboys sing at the dogs' funerals is: Miserere Dominus, miserere Dominus, Canis mortuus est, which translated into English is: Have mercy, Lord; have mercy, Lord; the dog is dead.
