<P> Some critics have suggested that the title is a reference to the metaphor "crocodile tears", a phrase that could be referring to Mia's insincere expressions of sorrow while committing a series of violent crimes . Jason Koebler of Vice notes that Mia does not read the End - User License Agreement (EULA) for the Recaller . Koebler suggests that Mia reading the EULA would have allowed her to avoid using the Recaller, and thus prevent her later murders from being necessary . </P> <P> Whilst series one and two of Black Mirror were shown on Channel 4 in the UK, in September 2015 Netflix commissioned the series for 12 episodes, and in March 2016 it outbid Channel 4 for the rights to distributing the third series, with a bid of $40 million . The 12 episode order was divided into two series of six episodes each . </P> <P> The episode was inspired by the series one episode, "The Entire History of You", which featured a personal implant that one could use privately to review their memories . For "Crocodile", they considered what the situation would be like if these memories were not private, developing a "cat - and - mouse type drama" that would highlight the importance of memories, and to what lengths one with a secret would go to hide those memories . </P> <P> The episode was initially conceived as having a male protagonist with Andrea Riseborough reading the script with another part in mind . However, after Riseborough liked the journey of the protagonist and asked if the part could be rewritten as a woman, the script was altered in order to accommodate Riseborough . Both Brooker and executive producer Annabel Jones described the change as interesting, with Jones noting that "How often do you see a mother reduced to this level of desperation?" on television . </P>
