The name of this episode refers to a line spoken by Dr. Jenner in TS-19 (2010) when Jenner traps Rick and the others in the control room of the C.D.C. After finally freeing Rick and the others and giving them a chance to live, Jenner tells Rick that "there's your chance," to which Rick replies that he's "grateful." Jenner then counters that "the day will come when you won't be." The horrific events of this episode are what Jenner was referring to.
During an European press tour in March 2017, executive producer and visual effects leader, Greg Nicotero, revealed at a panel that he originally tried to convince the heads of AMC, to air the season 7 premiere without any inclusion of break commercials. Greg explained that he would love to have a non-interrupted episode, because of the intensity of the episode. AMC declined.
First time Jeffrey Dean Morgan (Negan), Tom Payne (Paul "Jesus" Rovia), Austin Amelio (Dwight), and Xander Berkeley (Gregory) are credited as series regulars.
The number "4" on the bottom of Negan's bat (Lucille) represents that it's a 34 inch bat.
The first footage from this episode debuted on July 21, 2016 at San Diego ComicCon.
