When Rhodes and Emily Thompson are drinking "doubles" in the bar; as they converse, their glasses go from newly filled to almost empty to newly filled again within moments.
The letter Rhodes opens when arriving to Tijuana has the logo of the Ministerio de Justicia (Ministry of Justice) from Mexico. In Mexico, the ministries are called "Secretarías" (Departments) and justice is served by Procuraduría General de la República (Attorney's General Office).
