Factual error: On their way through the desert Nick and T. cross the Arizonian border. Shortly after that you see Joshua trees left and right. Joshua trees, at least in such abundance, are only found in Joshua Tree National Park, which lies in California. (00:14:20)
Factual error: The lasers shown protecting the office hit objects, like the desk. This should set the alarm off as it crossed and interrupted the laser beam.
