What in the Heck is Groundhog Day Anyway?
Was the 1993 film Groundhog Day really filmed in Punxsutawney?
Unfortunately, the answer is no. Columbia Pictures decided to film the movie in a location more accessible to a major metropolitan center. Punxsutawney is located in a very rural area with few highways, so Woodstock, Illinois was chosen as the site for the movie. As a result adjustments had to be made for the production. The actual Gobbler's Knob is a wooded hill with a beautiful view; the Gobbler's Knob in the movie is moved to the town square though it is recreated to scale based on detailed notes and videos the crew made on its visit to Punxsutawney.
