While showrunner Scott M. Gimple announced a couple weeks ago that Episode 1 of Season 4 had wrapped, Norman Reedus revealed that they had also finished shooting Episode 2 of Season 4. Norman Reedus said, “We just started Episode 3, and it’s amazing. It’s really, really good. You’re going to freak out.”
Cameras started rolling on Season 4 of The Walking Dead on May 6, so each of the first two episodes took about two weeks each to shoot. The Walking Dead Season 4 airs on AMC in the fall.
