I first had him speak normally--it was very clear right of the bat that he sounds like he's from the mid-west. Then I had him try a Southern accent. He managed to pull off a Kentucky/Tennessee dialect. It sounded kind of forced to start with, but the more he talked the better it got.
We ended up with him taking a short part as one of my nameless Confederate veterans. I had also considered the Tillis boy, but Bradley simply could not get "Negro" to come out properly without being prompted, so I scratched that idea. (I cannot say it like he did! :D)
All told, I think it was a good interview--even though I had a question I wanted to ask him about composing (he happens to be a composer) that I completely forgot about until after we hung up.
Skype is amazing...what a grand tool. It can connect people who are over 2,000 miles apart with a video call. Wow. What a blessing for us small time filmmakers! :)
