This movie was filmed mostly in Goldfield, Nevada. Though the fictional name Baxter was used. Goldfield is also nearly a ghost town that was booming during the gold rush. Since I have actually been to Goldfield I must say that if any of the filming was done in NY it must have been minimal and indoors since all of the scenery in the film is from either Goldfield or Jawbone Canyon.
I've been to Goldfield as well, that's why I asked the original question.
There's a few websites dedicated to Ghosttowns, and one of them told some about the history of the town. During the early 1900's, it was actually the biggest city in Nevada, with over 100,000 people. Once the mines dried up, people started moving away. Now, I don't even think there's 1,000 people in the County. When we would drive through there, and see the High School all boarded up, I never thought that at one time, this was a hoppin' little place to be.
I lived in Goldfield for 18 years when I was growing up. Tonopah is 26 miles from Goldfield has I had to ride a bus everyday for four years to go there for high school. I remember when this was filming and I met Christina Ricci. Sorry for the spelling I am in a hurry.
