The movie does take some creative liberties, but I don't think Billy Mitchell helped his case much. As I understand it, he may not have been actively avoiding Steve the way the movie implies. However, he probably is a douche in real life, and Twin Galaxies did botch some of the score submissions like was shown in the movie. The basic story as a whole (with Steve's scores being rejected at first, and Billy's sketchy tape, and Steve travelling around the country playing DK) is truthful, and I don't really understand why some people have acted like Billy is an angel and Steve is the real asshole. Just because they took some editing liberties doesn't mean that the complete opposite of what the movie portrays is the truth.
