MILWAUKEE (AP) -- With a film about John Dillinger hitting theaters, Wisconsin bankers and law enforcement officials are launching a campaign designed to deter bank holdups.

The movie "Public Enemies" follows the life of the notorious bank robber. Wisconsin Bankers Association president Kurt Bauer says the film portrays Dillinger as a folk hero rather than a dangerous criminal.

Authorities say that's a good reason to launch their campaign. It advises patrons to remove their hats, hoods and sunglasses while conducting bank business.

The goal is to make it easier to identify bank robbers. Bauer says people who don't comply will still be served, but "everyone in the bank will be watching them more closely."

The campaign will be formally announced Thursday afternoon.
