Zoo has been cancelled by CBS after three crazy seasons.
The series was adapted from the book of the same name by James Patterson but quickly went its own way.
In Zoo, humanity found itself slipping down the food chain after the world’s animals started violently attacking people. In season three, which aired over the summer, the year is 2027 and the world has reached a tipping point: as the human population continues to dwindle due to the sterility problem, an equally devastating threat rises in the form of “the hybrids,” an army of unstoppable lab-made creatures, hell-bent on destroying mankind.
The series starred James Wolk, Kristen Connolly, Billy Burke, Nonso Anozie, Alyssa Diaz, Josh Salatin, and Gracie Dzienny. Jeff Pinkner, Josh Appelbaum, Andre Nemec, Scott Rosenberg, Michael Katleman, Patterson, Bill Robinson, Leopoldo Gout and Steve Bowen served as executive producers.
