Co-writer/director Jeffrey Nachmanoff met with several intelligence professionals, political observers and other specialists to make his script as realistic as possible.
When Samir goes to the London home shortly after the bombing in Nice, a black taxi is seen passing in the street shortly before he enters the building. Next day he hails a taxi after getting off a bus. It is the same taxi. Whilst this is possible, it is highly improbable, given the number of black taxis in London.
During the scene where Samir is running into the apartment complex in Chicago while running away from the FBI agents, the original agents following him radio in that they are at the address "128 S. Randolph." There is no S. Randolph St. in the city of Chicago as Randolph runs East/West. However movie-makers frequently use nonexistent addresses, equivalent to telephone nos that start with "555-" to avoid legal issues.

No. Traitor is based on an idea by comedian Steve Martin, who is also the executive producer, and on a screenplay by Jeffrey Nachmanoff, who is also directing the movie.
