The adaptation of Arthur Herzong's novel, IQ 83, is reportedly in production, with a release date of this year (2013). Yet, I haven't seen anything posted about it for a while.
See, for example:
"An experimental virus made from modified DNA that effects intelligence escapes into the world's population and results in people losing IQ points. Civilization begins to rapidly break down as people start losing their skills; for example, airplane pilots take off but just a few hours later can't remember how to land their planes. The inventor of the virus is trying desperately to remain quarantined and find a cure but soon he is also exposed. Can he discover a cure before he forgets all there is to know about how he created it?"
The novel is a great little read, in any case. I heard James Franco is to star.
