The movie was released with the taglineMoscow's toughest detective. Chicago's craziest cop. There's only one thing more dangerous than making them mad: making them partners.
Russian Police Captain Ivan Danko sets a trap for Viktor Rostavili (Ed O'Ross), a Georgian drug dealer and crimelord. The ambush severely backfires; Viktor flees Russia and comes to the USA, after gunning down several other Moscow cops...including Danko's partner.
Loudmouthed Chicago PD Detective-Sergeant Art Ridžić (James Belushi) investigates several local murders committed by Viktor's cartel. Suddenly he finds himself partnered with Danko, who has chased Viktor here from Moscow with the intention of capturing the crime baron alive. Danko is frustrated when his lack of a diplomatic license prohibits him from carrying a weapon. He shares his candid observations with Ridžić: "This Chicago is very strange city. Your crime is organized, but your police is not."
Danko and Ridžić pursue Viktor and his henchmen around Chicago. Finally, Danko and Viktor commandeer a couple of Greyhound buses, then engage in a high-speed chase...until Viktor is side-slammed by a train. He takes on Danko in a running, Texas-style shootout (Danko uses a Ruger "Blackhawk" Magnum given to him by Ridžić); Viktor is gunned down. Danko returns to Moscow after exchanging wristwatches with Ridžić as an act of goodwill.
The film has gained cult status among Russian speakers, mainly due to its extremely poor Russian, numerous factual errors and portrayal of ethnic stereotypes.
Ivan Danko's police uniform is a combination of at least six different uniforms. His hat is a Moscow Commander's Special and he also wears a Parade Band Musician axelbant.
When Danko and his partner discuss the drug problem, the translation says they are referring to Miami while they were actually referring to Harlem. This has been corrected in the Momentum Pictures DVD, which has much more accurate translations.
The teleprinter at the Moscow militia headquarters is seen printing a message in Russian but in the Latin alphabet. Equipment used by the Soviet government would undoubtedly allow the Cyrillic alphabet to be used.
Ivan Danko uses the "Podbyrin 9.2 mm" handgun. It's actually a modified Western Desert Eagle .357 Magnum. The Podbyrin does not exist and was made up as a prop for the movie.
The French title of Red Heat is Double Détente, a reference to the Soviet-American détente of the 1970s.
Ridžić, (although pronounced as: "Ridzik") is a Serbian family name (originally pronounced as IPA: [riˑdʒitʃ]) originating from Bosnia, and the city of Chicago is known for its sizable Serbian population.
The Moscow car chase scene, where Lada cars pursue one another through the old city, were actually filmed in Budapest, Hungary. Russian roles were played by Hungarian actors with their original voices speaking Russian. The Moscow Police Headquarters scene was filmed at the internal yards of the Buda Castle in Budapest.
In the Moscow obscure cantina scene several famous Hungarian actors are appearing among them Norbert Növényi and Gábor Koncz. Other two Hungarian famous actors are Péter Trokán and János Bán as policemen at the Headquarters.
This movie is referenced in My Way Entertainment's dub video, "J3: Return of the Colossi."
