In the film “The accountant”, a man on the autism spectrum is a number cruncher by day, while involving himself in seedier activities at night.
This scene occurs in a conference room after the lead character, Christian (Ben Affleck), is hired to review a company’s financial records. He spends an entire night writing out figures, using whiteboards and eventually the room’s glass walls.
For the scene, Mr. O’Connor wanted to take the audience inside the mind of the character. During an interview, he explained how he used a real forensic accountant to get the numbers right and also a creative approach to covering walls with tidy handwriting.

Twenty-First Century Birdwatching
Our ancestors could spot natural predators from far by their silhouettes. Are we equally aware of the predators in the present-day? Drones are remote-controlled planes that can be used for anything from surveillance, to rescue operations and scientific research. Most drones are used today by military powers for remote-controlled surveillance and attack, and their numbers are growing. The Federal Aviation Administration (FAA) predicted in 2012 that within 20 years there could be as many as 30.000 drones flying over U.S. Soil alone.
