The gang from the "Hangover" film franchise will apparently be filming the third and final installment in Nogales, Ariz.

   The Tucson Film Office, which has remained mum on exactly what movie is being filmed in Nogales, posted a picture on its Facebook today taken by a resident of the border city. "Warner Brothers is changing up my hometown, Nogales Arizona, to look like Tijuana Mexico, for the filming of 'The Hangover Part 3'," according to the post.

 No word from the film office beyond this and no word from the producers, who have kept an extremely tight lid on the project. The plot, as reported by Screenrant.com, has the guys back on the road, but this time they are heading to a mental institution to break out Alan (Zach Galifianakis).
