Cumberland University
I saw a scene in the trailer where Billy is on these stairs with all these animal heads on the wall. I am pretty sure that it was filmed in the clock tower building at Cumberland University, which is in Lebanon, TN where some of the movie was filmed.
I was there over the summer as a counselor at a Christian summer camp. I had a hard time walking up those stairs because the animal heads made me uncomfortable and a little sad. Mostly the giraffe.
I was mostly just excited so I thought I'd share.
If anyone has any additional information about the school in relation to Billy Graham, that would be great!
