Animals once ruled the Earth. What if they decide to take it back? Thats the tagline and the preimse of Zoo, based on James Pattersons novel, which sees a huge number of violent attacks by animals on humans across the world. James Wolk stars as the young scientist who takes it upon himself to figure out what exactly is going on, and how it can be stopped before its too late. Its a welcome return to screens for Wolk, best-known for his role as the mysterious Bob Benson in Mad Men. Hell be helped by the likes of Kristen Connolly (House of Cards), Billy Burke (The Twilight Saga) and Nonso Anozie (making his second appearance on this list). Its an interesting idea and certainly looks as though itll contain plenty of thrilling moments, as well as enough animals to fill an arc.
