Calvin Reid at Publisher's Weekly talks to Radical Publishing about their publishing philosophy and their upcoming plans:

“We're a publishing company on a broad scale,” said Levine during an interview in Manhattan. “It's the easiest way to brand ourselves and control our properties. We offer great content with multiplatform opportunities. Our books can stand on their own, and the films help them appeal to another segment of the audience.” Levine, who is Radical's president and publisher, called the house's movie plans “marketing strategies” that are used to cross-promote the graphic novels.

In addition to movie versions of their Hercules, Caliber and Freedom Formula comics, the article also hits on their planned move into prose publishing:

In addition, the house is negotiating with New York trade houses to create prose novelizations of its comics, and Matt Fleckenstein, a writer on the animated TV hit Family Guy, is developing Animal Square as a kids' book and animated film. And in 2009 the house will publish a series of lavishly illustrated prose novels (each with 30 to 45 pages of artwork), developed by pairing writers from its comics list (“comic book writers are all frustrated novelists,” said Berger) with artists from the Storm Lion manga studio.

That last quote was surely said in jest, right?
