Greg Nicotero wanted the cow to look eviscerated, so he bought real entrails from a butcher shop. The outside temperature was so high, the entrails steamed on their own at first.
Unlike most episodes, the theme music is not played over the closing credits. Instead there is only silence.
The conversation between Rick & Carl about Carol's mental state after losing her daughter, is similar to the comics except the roles are reversed.
Only one walker is seen in this episode.
