And that is how Fritz Lang's 1931 film M starts. Reminiscent of A Nightmare on Elm Street's "One, two, Freddie's coming for you...", the children's rhyme in M does two things: it lets you know that there is a killer on the loose, but it also speaks to the "it won't happen to me" mindset of the children. Kids being kids, they worry about nothing at their own peril.
