The mural on the back wall of the dining room is "The Banquet of the Officers of the St. George Militia of Haarlem" (1616) by Frans Hals. It became the basis for Peter Greenaway's set decoration & costuming in the dining area.
Peter Greenaway uses specific colors to represent each set of the film. The exterior of Le Hollandais is predominantly blue. The kitchen is mostly green. The seating area of the restaurant is red and the restrooms are stark white. The color of Georgina's dress and the sashes that Albert and his associates wear change to match this scheme as the characters move from room to room. The color of Georgina's cigarettes also changes to match the color of the set as she moves.
The four title characters are named for the actors writer-director Peter Greenaway originally wanted to play them. Richard (The Cook) is for Richard Bohringer, the only one of Greenaway's original choices retained in the final film. Albert (The Thief) is named after Albert Finney, while Georgina (His Wife) is for Georgina Hale. Michael (The Lover) is named, interestingly enough, for Michael Gambon, whom Greenaway eventually re-cast as Albert.
The car that Albert Spica drives is listed in the credits as a Valentine Lindsay AT V12. It is in fact a modified early-'70s Dodge Dart Swinger. Valentine Lindsay is the name of a British car enthusiast and racer who works with the V12 Team of Harrier Racing, and most likely loaned the car to the production.
