I thought I'd add to the previous post 'Fleeting Details' with this talk about how to use mystery, by someone who specialises in it. And who specializes more in mystery than the Executive Producer of both Lost and Alias as well as the Producer of Cloverfield? No one, that's who.
Except Alfred Hitchcock... and David Copperfield... okay, so there's a couple, but none of them recorded a speech at TED which I have posted here, have they?
This video talks about the bigger mysteries in a story, rather than the smaller details that never have to be resolved. It's a very interesting listen.
We'd love to hear some examples of what you think are badly done mysteries. Withholding information from an audience is a fantastic technique, but where has it gone wrong for you?
