I'm pretty new to filmmaking and would like to film a short trailer in the downtown location a city in Ohio. Can anyone tell me how hard it is to film in a downtown location? What are the details involved? I plan to contact the film commission of the city, but wanted to get some ideas of whether it's an extremely difficult thing to do. I'm thinking I'll need traffic detoured from a certain road while filmming. How difficult would that be and is it expensive to achieve if filming only lasts a day?
