Frank Miller

Frank Miller is a famed comic-book writer. According to Flint Dille, he was involved in writing The Transformers: The Movie. While Dille and others were rehashing the end of the script, Steve Gerber brought his friend Miller in to help out. In return, they helped Miller with the ending of the Batman book he was working on.

Dille says this began a long-running friendship, and they still contribute to each other's work.
