It's really difficult to tell at times, movies film under code names for their permits to help prevent fans from showing up as much as possible. The police dept or city will have a record of who received the permits but many times it wont tell you what exactly is being filmed. I would not reccomend showing up to try to.look either. Movie/TV sets are generally closed for liability reasons.
Call the Fairburn Police non emergency number. If someone is filming there, they have to have a permit. The police will be more than happy to tell you.
