LA-based Radical Publishing, which is busy setting up adaptations of its comic book imprint Radical Comics around Hollywood, has acquired a 20% stake in Singapore’s media conglomerate, Storm Lion.

Edmund Shern’s Storm Lion is involved on the 3D anime title Yona Yona Penguin and serves as executive producer on Split Image’s Indian mythological tale Hisss, which Endeavor Independent is selling in Cannes. Storm Lion is also a licensed content provider for the Apple iPhone and other mobile devices.

Meanwhile, Radical Publishing has attached Jamie Mathieson to adapt the screenplay of Radical Comics’ Hotwire mini-series, based on an exorcist detective in a futuristic London.

Previously announced projects include Peter Berg on board to direct Radical’s Hercules set up with Universal and Spyglass, Bryan Singer set to produce and possibly direct Freedom Formula set up at New Regency, andJohnny Depp’s Infinitum Nihil producing Caliber.

“The relationship between Storm Lion and Radical is integral to our growth,” Radical Publishing president Barry Levine said. “It allows us to have access to intellectual properties that are indigenous to Asia, but that have the potential to cross over for potential development as published works and other ancillaries in North America and worldwide audiences.”

UK-based Intandem Films handles sales for the Radical slate and owns a 10% equity stake in the company.
