Filming took place over a 34-day period during the fall of 2019 in New York's Hudson Valley, where the story is also set. Forty local crew members were hired and over 500 background extras were booked through Hudson Valley Casting. Tech City (former IBM HQ) in the town of Ulster was rented for months as the qualified production facility and for administrative office space. Over 4,400 rooms were booked at regional hotels and the local spend was north of $13 million. Locations were used throughout the region thanks to the talent of (location manager) Kurt Enger and his crew, including Myna Joseph. Featured locations in the film were found in Millerton, Red Hook, Tivoli, Kingston, Palenville, and Ulster, in Dutchess and Ulster Counties NY.
