Gerard Butler and Alan Siegel’s G-BASE productions has acquired rights to V.E. Schwab’s fantasy novel A Darker Shade Of Magic for series development. Butler, Siegel and Danielle Robinson will produce with Schwab writing the pilot. The project is being eyed as a limited series.

The book is set in four parallel worlds, with four parallel Londons ruled by different magical powers and monarchies. Grey London, where the people have been told that magic is a myth; Red London, where magic is embraced and thrives; White London, where magic is used by the rulers against it’s people; and Black London, where magic has overpowered the people and corrupted the world beyond repair.

Schwab is also the author of Vicious, which is set up at Story Mining with Scott Free producing. She is repped by CAA and Waxman Leavell Literary.

G-BASE is behind upcoming feature London Has Fallen (Gramercy/ Millennium), the sequel to box office hit Olympus Has Fallen. They recently finished shooting The Headhunter’s Calling for director Mark Williams and Voltage Films in Toronto. G-BASE is repped by CAA and Gray Krauss Stratford Sandler Des Rochers LLP.
