According to Frankenheimer, French authorities helped him circumvent a strict Paris ordinance that prohibited film productions from firing guns in the city. This was enacted because many civilians had been complaining about the gunfire noise produced by film shoots. Additional factors influenced the decision; officials' desire for an American action film like Ronin, few of which had been filmed there since the law was passed, to be filmed in Paris and the desire to boost France's reputation as a filming location.
