For those interested anime-pulse has an interview of John O'Donnell on their site. It's from 2006, and it's a good listen. They also have it typed up if you don't want to listen to it, but would rather read it.
And yes he says in this podcast as well that "MD Geist" is his favorite anime. But another title he mentions liking is "Grave of the Fireflies". His favorite american comic book/American manga is "Project A-Ko" which was based off of the "Project A-Ko" anime.
