Our picture book app Hilda Bewildered makes use of a doppelgänger, who may or may not exist in the real life of the story. The purpose? To demonstrate the theme: That there is really not that much difference between rich kids and poor kids other than circumstance of birth. Or as I heard Julian Fellowes say in an RNZ interview, in his experience there are genteel, good-looking and smart people to be found at every level of society.
The ghost writer of this Alfred Hitchcock novel from 1978 used the concept of the doppelgänger in a very camp way. Read accordingly.
But we all have doppelgangers, if you expand the concept a little.
WHAT IS A DATA DOPPELGANGER?
If you’ve ever taken more than a brief glance at the ‘personalised’ advertising directed at you by companies such as Facebook, you may identify with the following:
Google thinks I’m interested in parenting, superhero movies, and shooter games. The data broker Acxiom thinks I like driving trucks. My data doppelgänger is made up of my browsing history, my status updates, my GPS locations, my responses to marketing mail, my credit card transactions, and my public records. Still, it constantly gets me wrong, often to hilarious effect. I take some comfort that the system doesn’t know me too well, yet it is unnerving when something is misdirected at me. Why do I take it so personally when personalization gets it wrong?
DOPPELGANGERS IN FILM
See this list: 20 Films About Doubles And Doppelgangers. Can you guess the most famous one?
The double/doppelganger is a subcategory of the trickster archetype. (Click through for a mindmap of tricksters in storytelling.)
Changeling: You may be familiar with the film starring Angelina Jolie. See John Truby’s breakdown — for him the film didn’t work. Did it work for you?
Twins are also used a lot in storytelling. Often one is evil; other times both are evil, and since two minds are better than one by an order of magnitude, this is useful for storytellers.
