Backwards Induction in The Lookout
The lead character has trouble sequencing his actions (wake up, shower, eat, get your keys, lock the door, etc.) due to a brain injury. So his roommate tells him to stop thinking of it as “sequencing,” and tell a story instead. Ho-hum. But then his roommate adds that he should start with the way he wants his day’s story to end, and work backwards from there, step by step.
I don’t think it’s much of a spoiler to say that in this movie, backwards induction turns out to be a very useful skill indeed!
