Trivia: The diner Howard goes into after pushing his car is Mickey's Diner in downtown St. Paul, Minnesota. The same diner was used in The Mighty Ducks, also shot in Minnesota. In this film however, the interior is a set. The interior of the real Mickey's Diner is not as spacious as shown in the film.
Trivia: The parade scenes were filmed on the Universal Studios backlot in "Courthouse Square." The film's special effects artists then digitally composited in some elements of a street in the Twin Cities, Minnesota, where the film is set. The sequence took three weeks to shoot and involved hundreds of extras.
