UPDATED: Kevin Spacey-Jon Hamm-Jamie Foxx-Ansel Elgort movie filming near Perimeter Mall

A movie with Kevin Spacey, Ansel Elgort, Jamie Foxx, Jon Hamm and Eiza González has brought stars and stargazers - and some planned road closures - to the busy Perimeter Mall area.

"Baby Driver," about a crime boss' young getaway driver who finds himself embroiled in a doomed heist, is filming at a former bank branch location on Ashford Dunwoody Road, right across from Perimeter Mall, through Friday.

The project involves a bank robbery (naturally). The gun fire will be fake but traffic impact will be real. Some road closures are planned - see below.

Christina Burdick, Amanda Stanford and Sarah Cory were among the fans standing on the periphery, hoping to glimpse someone famous.

"This doesn't happen every day," Cory noted.

Burdick said traffic seemed to be moving OK despite the action.

"I thought it would be a lot worse," she said.

That could happen. Today's action mostly involved the robbers sitting outside the bank, hatching their heist. Driving scenes will start later in the production schedule and will cause some temporary road closures.

Still, they didn't seem to mind. They spent a good bit of time watching on Wednesday, and learning what all goes into making a movie. "It makes you appreciate movies so much more. We've watched for hours and it's probably going to be five seconds (on screen)," Burdick said. "They work so hard."

Stephanie Moshier, Terri Wigger, Ashley Campbell and Evan Gilchrist stood under a shady spot to watch, and happened to meet one of the stunt drivers involved with the upcoming scene.

Gilchrist probably spent more time than anyone on set outside the folks officially involved.

"I've been out here since 10 a.m.," he said about 5 p.m. Traffic had been fine throughout the day, affected only during a brief time first thing in the morning, he said. They didn't seem worried about impact over the next few days.

"I'm from Kentucky," said Campbell, who now lives in the area. "This is interesting."

From the production folks:

"The film company, Bambino Films, LLC, will be filming scenes for the upcoming motion picture "Baby Driver" in the Perimeter area.

The filming dates are currently scheduled for Wednesday, 3/16, Thursday, 3/17 and Monday, 3/21, between the hours of 6:00 am and 8:00 pm.

The majority of the activity will be on private property located .. on the corner of Perimeter Center West directly across from the Exxon on Ashford Dunwoody. (NOTE: The notice from production folks referred to this location as a "Sun Trust building." This is a former branch location - SunTrust does not own the building and is not involved) on the corner of Perimeter Center West directly across from the Exxon on Ashford Dunwoody.

Throughout those three days, the filming company will be filming scenes of a SIMULATED bank robbery, which will involve fake GUNFIRE and driving stunts on the property.

During the hours of 9:00 am and 11:30 am, on all three - 3/16, 3/17 & 3/21 - the film crew will be temporarily holding traffic on Ashford Dunwoody Rd. between Perimeter Center East/West (McDonald's) and Hammond Dr., to perform driving scenes on Ashford Dunwoody Rd.

Please expect traffic delays during these times. The film company asks that you plan accordingly. The Dunwoody Police Department will be assisting with the traffic management and will be on site for all filming activity.

Bambino Films, LLC will make every effort to minimize the impact on the neighborhood/Perimeter area."
