That it's possible to have a 4 digit IQ.
Other than that, I really enjoyed that movie....
EDIT:
From the movie Limitless.
For those that don't understand, IQ's are based on a distribution curve. ie, they're based on the worlds population, and basically indicate which percentile you fall in. Depending on which scale you're using, usually 100 is 50th percentile. So, again based on the particular scale, the highest IQ possible is around 195 or 205. Maybe when the worlds population hits 100 billion will a 4 digit IQ be possible.
No matter how much smarter then second place you are, you will always only be one IQ point higher.
