  • McLeaned: Dale. Jeffrey DeMunn, who was a long-time collaborator and friend with showrunner Frank Darabont, asked to be written out when Darabont was axed. He later had second thoughts, but by then it was too late.
  • Significant Series Premiere Date: The pilot episode aired on Halloween of 2010.
  • Spoiler: The details of the blu-ray release of the second season were released before season two was over. The blurb said that the release included Shane's last episode. Non spoiler news story here.
  • Throw It In: The barn's collapse in the season finale was not scripted.
  • What Could Have Been: Had Frank Darabont not been fired, the second-season premiere (as indicated in preview trailers and leaked information from various sources) would have resolved the "Vatos" plotline introduced in the first-season episode of the same name. After leaving the CDC, the group goes to the Vatos camp to warn them that things are much worse than they expected. They find the retirement home overrun (with Guillermo and the rest of the Vatos recently killed), and proceed to take down every walker in the vicinity before having to hide. Shane almost gets overtaken by a mob of walkers while escaping the home, and is saved by Dale in his R.V. The encounter with the horde of walkers on the highway is the only major remnant of the original premiere (as most of the footage was, according to AMC, "unusable") - in total, just 1/3 of the filmed material remained. The Vatos resolution also counts as an Aborted Arc.
    • In addition to this, there was another series of webisodes planned which would have explained the story of the soldier walker in the tank; who, as it turns out, was played by Sam Witwer. But with Frank Darabont being fired, his plan for this fell through. According to Witwer, there were dozens of other little things like this that Darabont had plans for in the future.
