Although the movie was filmed in the Carolinas and not Duluth, Clooney says they wanted to pay tribute to Duluth for serving as the setting for "Leatherheads."
At a news conference he explained, with some understatement, why the film wasn't shot in northeastern Minnesota. He says he understands that in Duluth "it's cold in February."
Clooney says he studied old screwball comedies like "The Front Page" to adopt their style to his new film.
"Leatherheads" opens April 4.
