Walden Media

Walden Media is a film production and publishing company best known as the producers of Sonic Cinematic Universe alongside with Nickelodeon Movies, Annapurna Pictures and Everest Entertainment. Its films are based on notable classic or award-winning children's literature, compelling biographies or historical events, documentaries and some original screenplays. 
The corporate headquarters of Walden Media are located in Century City, California, and the Education, Outreach, Interactive and Publishing offices are in Boston, Massachusetts. 
Walden Media was created in 2001 by Michael Flaherty and Cary Granat. Granat was president of Miramax's Dimension Films division, and Flaherty came from the world of education. Flaherty was called an “entrepreneur in education” by the Boston Globe for his work with innovative programs meant to help underprivileged students gain access to quality education. The two were housemates at Tufts University before following different paths and then reuniting to form Walden Media as a movie, television, publishing and Internet enterprise whose goal is to teach and entertain kids. The company is owned by the Christian conservative Philip Anschutz, who has said he expects their movies "to be entertaining, but also to be life affirming and to carry a moral message."
In September 2014, Annapurna Pictures and Walden Media set up a joint venture animation and motion-capture facility, Annapurna/Walden Digital, a London-based film animation and motion-capture company, where Ellison would produce Sonic Cinematic Universe films using performance capture technology.
