The actress revealed that much stranger things happened while filming on location in Clarkesville, Georgia.
According the The Sun, she said: "You do get nervous when there's a day where it's, 'Oops, I'm naked'. I wouldn't go topless for a cause, going to such an extreme to make a difference. But we've been among these people in this environment for almost two months."
"The topless scene was nothing compared to what happened in the two months prior. There was an actor naked the whole time getting his touch-ups and everybody else just having a normal conversation."
Speaking of shooting the movie, she added: "There was a real community feeling. We were in the middle of nowhere and we were all a hop, skip and a jump from each other, peppered around this lake. The farthest people were 20 minutes away. After work we had dinner together and we spent the weekends together."
Aniston also confessed that she would love to move to the country since she felt a sense of anonymity while filming in Clarkesville.
"It was the greatest experience because I felt like I gained my anonymity back. I was like, God, I'm so paranoid and pent up. You realise how paranoid and guarded and non-trusting... There was a sigh of relief to be able to walk around like a normal person and feel like I've got my anonymity back," she concluded.
