A real bank heist took place near the filming location and the felons drove right past the PA who immediately alerted everyone on set. The felons were surprised to see that they were driving through a film set, shortly before driving headlong into (and becoming hopelessly stuck in) a fake snow drift. The police immediately apprehended the two bumbling crooks to the amusement of all on set.

This film was originally planned to be "The Adventures of Pete & Pete" (1993) movie.
The news anchor woman in the movie (Andrea Engel) and the Sportscaster (Shaye Ganam) are real life news anchors for a TV station in Edmonton, Alberta, where the exterior shots were filmed.
The news studio where Chevy Chase reports his weather is an actual news studio in Edmonton, Alberta. A local Meteorologist used a similar board for reporting the weather, almost like what Chase acted out. In the distance, you can see the news anchors from Edmonton, who also starred in this movie.
Chevy Chase complained on "The Rosie O'Donnell Show" (1996) that when filming in Edmonton Alberta, Canada, it was incredibly cold outside. In fact, the temperature throughout filming was +1C (34F) or higher everyday. Effects artists actually had to *make* snow for the shooting. Then mayor of Edmonton, Bill Smith, sent a letter to Rosie O'Donnell telling the truth of the matter, which she read on air and laughed off - to the annoyance of most Edmontonians.
