Hangover stars greet Nogales residents during filming

Bradley Cooper and Zach Galifianakis, stars of the Hangover movies, made an appearance in Nogales Tuesday night.

The crew is on location, filming the new Hangover 3 film.

Viewer Mike Lerma sent us a video of the stars waving to the public.

Shooting for the new film began last week, and is expected to wrap up later this month.

Producers have turned the small town of Nogales into Tijuana.
