Tragically, we will probably never see an adaptation of the superb “Understand”, because “Limitless” (2011) already used mostly the same premise and fucked it up horribly. Read it here! It’s legal and a fine use of a reasonably small fraction of your time.
“Seventy-Two Letters” would still probably kickass, though.
It’s too bad we don’t have “The Outer Limits” around anymore for things like this.
