Stories from the set

The International Hotel, where David, played by Miles Teller, is staying, is not in Albania but in the center of Bucharest, the capital of Romania.

The events set in Albania were filmed in Romania. Even the workers at the warehouse in one scene speak Romanian.

The film was initially titled the same as the Guy Lawson article it is based on — «Arms and the Dudes».

The film is based on real events.

The original title of the film translates as «War Dogs».

The film's poster is a parody of the famous poster for Brian De Palma's crime drama "Scarface" (1983), which the main characters of "War Dogs" constantly reference.

For secrecy during filming in Miami, the film was called "AK-47".

The arms manufacturers' forum in Las Vegas that David and Efraim attend is a fabrication of the film's writers, but in real life it has analogues. SHOT Show — the world's largest exhibition of equipment and gear for hunting and shooting sports — takes place once a year (usually in January) and lasts four days, in recent years in Las Vegas. The tanks, rockets and other military equipment shown in the film were filmed at IDEX — the international defense exhibition and conference held every two years in Abu Dhabi, United Arab Emirates.

The role of Iz is played by actress Ana de Armas, who is of Cuban-Spanish origin. In Spanish, her surname means "weapon".

Jonah Hill and his character Ephraim Divoroli were born on December 20.
