The Walking Dead season 3 finale on March 31 managed to break a new ratings record for the cable hit. 12.4 million viewers tuned into the final episode of the season which saw the death of a major character. The previous record-holding episode was the February 10 midseason premiere which garnered 12.3 million viewers–the finale just beat it out. 6.8 million in the coveted 18-49 demo watched this episode, another all-time high for the series.

AMC president Charlie Collier: “Two words: Grateful. Dead. It’s a joy that we get to work with such tremendous talent to makeThe Walking Dead and Talking Dead come to life for audiences that continue to engage and grow. In just three seasons, The Walking Dead has become a pop-culture phenomenon, entertaining millions of passionate viewers and obliterating traditional lines between cable and broadcast television.”

Now check out this preview of season 4 which is set to debut on AMC in October. Though you won’t find new footage, you will hear tantalizing tidbits from the show’s producers and stars. “There’s a broader, bigger world out there. Now that we’ve introduced that there are more survivors out there, it’s only going to get more and more interesting,” says EP David Alpert. “We will be getting into more world building, more civilization being brought back, more of a bigger sense of community,” spills EP and Walking Dead comic book creator Robert Kirkman. “The Governor is still out there. The war is not over,” shares EP Denise Huth. Fans can also expect more transformation out of trigger-happy Carl. “Is Carl going to be Rick? Or is Carl going to be The Governor? Right now it can go either way,” posits Huth.
