CBS is eyeing a drama based on aspects of Robert Ludlum’s novels about the spies who work for the secretive Treadstone Corp.

Project is in the early stage of development for CBS and CBS TV Studios. Eye has ordered a script to be penned by scribe John Glenn, who will exec produce. “CSI” maven Anthony Zuiker is also on board as an exec producer.

Glenn’s past credits include the recent remake of “Journey to the Center of the Earth.” He’s also penning a drama pilot for Fox and Chernin Entertainment about vigilantes in New York City.
