* More than 620 drawings were made for the sets.

* There are two different studios involved in CCUS, one in Culver City, California, and the other in Bristol, U.K. The distance between these two is 5,375 miles

* If you look closely, there are subtle references to different things on the sets. The book in the Toucan shot is named after a prop maker's niece and the pet help books on the shelf in the pet shop have old CREATURE COMFORTS animals on.

* Among other things, the series pays visual homage to the famous painting "American Gothic," the Groundhog Day holiday, the space program and a Minuteman statue. There are also several icons of the American landscape in the background of shots, including the Empire State Building, Mt. Rushmore, the Golden Gate Bridge and Monument Valley.
