Filming for the upcoming Kevin Hart/Bryan Cranston movie Untouchable is officially underway in Philadelphia.

Hart and Cranston were spotted filming on Monday in Center City, driving by City Hall and down Broad Street in a silver Ferrari. In the scene in which Hart's character drives Cranston's character to an art gallery. The pair also traveled down Pine, 16th, and Market Streets for the filming, gossip correspondent and photographer HughE Dillon says. Filming, which lasted from 9 a.m. to noon Monday, did not close any streets.

Often times, cars featuring actors driving in vehicles are filmed by towing the vehicle. As photos from Dillon show, Hart actually drove the Ferrari around Philly with a camera rig strapped to the car's side.

The Ferrari used in Monday's 'Untouchable filming' used a camera rig attached to the side of the car to capture the action inside the vehicle. 
The stars were accompanied by three police cars, two in front and one in back, during filming. That, however, did not deter some fans from catching up to the car for a selfie with the stars, or Cranston and Hart from waving at fans between takes.

The Untouchable crew also filmed at the Center for Architecture and Design, which Dillon says will serve as a stand-in for the above-mentioned art gallery in the film. Pia Mechler, a German actress known for her work on the web series Almost Settled, plays the gallery's owner.

Dillon also spotted at least one taxi cab van that appeared to be dressed up like an New York City cab at the shoot, meaning that Philly here may be serving as a stand-in for the Big Apple. Crews are also currently working on the movie in New York, according to the Mayor's Office of Media and Entertainment. Late last month, filming notices were spotted in Manhattan, entertainment blog On Location Vacations reports.

While filming this time around didn't close any streets, a previous round of shooting closed several Center City streets last month. Hart and Cranston were not involved in that round of shooting.

Untouchable is a remake of the 2011 French hit, The Intouchables, which tells the story of a white millionaire who hires a black caregiver following a paragliding accident that leaves him paralyzed. Hart and Cranston have been attached to the project since March 2016, with news of actress Nicole Kidman joining the cast breaking in Jan. 2017.

Most recently, How to Get Away with Murder's Aja Naomi King signed on to the Untouchable cast, Deadline reports. King is known for her role as Michaela Pratt on Murder, and appeared as Nat Turner's wife, Cherry Turner, in 2016's The Birth of a Nation. As Dillon reports, The Good Wife star Julianna Margulies is now also attached to the project as "a love interest of Bryan Cranston's."
