Pep has a subtle Texan accent, which is remarked upon quickly by Caura.
Mitch wearing the pirate outfit served two purposes: 1)That scene plus another were a re-shoot and Paul's hair had since been cut, and 2) Was improvised to liven up the sequence.
All of Mitch's phone dialogue after Pep hangs up is improvised. He speaks of a village, which Pep also used (also improvised). Paul had no idea Cole used the village line when he'd said it.
A deleted scene where the two main characters converse in gridlocked traffic was shot on the rooftop of a parking structure. It was cut because Pep took more than half an hour to get back to his office, and moreover, the plot.
The ending was re-shot after the original footage was unsatisfactory, which took place a couple of months after wrap. The dialogue was re-fitted by Siegle and Cole.
