Much of "Animal House" was filmed at the University of Oregon and in Eugene. (Several school refused to allow it to be filmed on their campuses.) The homecoming parade scenes were filmed in the town of Cottage Grove, OR. I spent a night outside of Cottage grove during the 2007 edition of Cycle Oregon. Took the shuttle into town and walked the main street. (May I have 10,000 marbles, please!) At I home I have a photo of a restaurant sign that can be seen in the film.
