"There he is! There he is!"

The excited scream ripped through the stifling summer afternoon in downtown Lockport, alerting the crowd of onlookers who were wielding phones and digital cameras.

More than three dozen people were crammed onto a stretch of sidewalk on 11th Street, waiting for a sighting of actor Johnny Depp. He was scheduled to film the final local scenes of the movie "Public Enemies" on Friday afternoon, and clearly the word had spread.

At 10 a.m., people already were lining up on the streets. It wasn't until about 1:30 p.m. that Depp appeared, costumed in a white dress shirt, brown pants and suspenders. He got out of a navy blue Ford Expedition at 11th and State streets. When he heard the screams from the crowd, he smiled and waved politely but continued walking north on State Street.

Hardly anyone had been ready for the brief sighting. But they would have other chances Friday - filming was slated to go until 9 p.m.

In the meantime, spectators were treated to State Street traffic being shut down in both directions so old-time cars could drive a loop of about four blocks of the street. Extras in period costumes walked across the street and milled about on cue, resetting themselves several times for the same take.

At one point, "Public Enemies" director Michael Mann stepped onto the sidewalk and talked on a cell phone. He didn't acknowledge the crowd, who urged him to turn around and pose for a picture.

Sharon Gort, of Lockport, was waiting with her daughter, Lex, 13, and her daughter's friend Mia Cochrane, 13, of Homer Glen. They arrived about noon and were shuffled from spot to spot by police and movie personnel.

"He's supposed to come to this place (Mama's Onesti's restaurant) and walk in and deliver a package," Sharon said of Depp.

Lex had brought a silver marker in hopes of getting Depp to sign her "Sweeney Todd"-style bowler hat.

Not all the onlookers, however, were Depp fans. Some liked the idea of seeing an actual movie being shot. Connie Kabellis, of Homer Glen, was one such fan.

"I just like to watch the whole filming process," she said. "I'm amazed that it takes hours to film one short scene."

As the afternoon wore on, the crowd of onlookers grew.

"Think of all this excitement in little Lockport," said Rob Weierman, of Lockport, who was with his son Mike Weierman, watching filmmaking for the first time. "But hopefully not the last. I hope they use Lockport more for filming."

"Public Enemies" is slated for a 2009 release.
