When I was in school, I was very much into just sports, mostly basketball, and didn't really see myself as much of a student. But once I got into college, I figured I wasn't going to be play beyond college. I started to think what was I going to do, since I wouldn't be able to make a living with basketball. There were a couple of things I liked to do. I wrote poetry, spoken word mostly.
A changeling is one child substituted for another. I couldn't find anything more apt. We had to kind of fight that supernatural element in the publicity, and I offered to try and find another title, but Clint liked it, and it stayed.
