Where was Animal House filmed?

Left off on purpose. Cancelled shoot: The Wikipedia article for this production names University of Missouri in the part this atlas reads for filming locations, and this atlas does not show it. The article says the University of Missouri gave consent to shoot the film at the college, but its president withdrew permission after reading the script. The shoot went to the University of Oregon in Eugene, which the atlas shows. Source. Cancelled shoot: The Wikipedia article for this production names Columbia (Missouri) in the part this atlas reads for filming locations, and this atlas does not show it. Columbia is named only as the home of the University of Missouri, in the sentence that says permission to film there was withdrawn. Nothing was shot in Missouri. Source. Not a shoot: The Wikipedia article for this production names Denver in the part this atlas reads for filming locations, and this atlas does not show it. The sentence the atlas read is about the first preview screening, which was held in Denver four months before the film opened nationwide. A screening is where the finished film was shown to an audience, not where it was shot. The shoot was in Oregon, at the University of Oregon in Eugene and in Cottage Grove, which the atlas shows.
