There Be Dragons
There Be Dragons is a 2011 war film following the early life of Josemaría Escrivá, founder of Opus Dei (Work of God), told through the flashbacks of Manolo Torres, a fictional friend of Escrivá. Most of the story is told during the Spanish Civil War, where Torres struggles with being a spy for the Nationalists whilst fighting alongside Republicans, and Escrivá struggles with being a Catholic priest in Republican-occupied territory.
The following weapons were used in the film There Be Dragons:
Mauser C96 "Red Nine"
Argentine Mauser 1909 Carbine
The Argentine Mauser Carbine is by far the most seen weapon on screen, easily identified by its distinctive endcap and bayonet lug. This was likely intended to stand in for the similiar Spanish M1895 carbine, and was used due to the filming in Argentina. It is used by Manolo and Ildiko, and also by various Nationalist and Republican extras.
1911s are seen in the hands of Republicans throughout the film, most notably used to execute a Catholic Priest.
Argentine Mauser M1909
Argentine Mauser rifles turn up quite a bit in this film, always in the hands of extras, and never fired, standing in for Spanish M93s.
An FN MAG is used by Nationalists. The gun is an anachronism, but was probably used to impersonate a machine gun of the period, as it is only seen for a few seconds.
M3A1 Grease Gun
An anachronistic Grease Gun is seen in the hands of a Moroccan Nationalist soldier.
Labora Fontbernat M1938
When Oriol has to fire his Thompson, it is replaced by an Labora Fontbernat M1938 SMG mocked up to look like a Thompson.
A Ballester-Molina is used by Oriol to kill himself so he didn't have to execute Ildiko. Again likely used due to the filming in Argentina, and standing in for the Star Model A widely used in the Spanish Civil War.
T-26 Light Tank
A Soviet-made T-26 appears in one of the battle scenes. During the Spanish Civil War, the Soviet Union was the only country to overtly supply the Republicans with heavy equipment. Interestingly, only Russian crews were allowed to crew these tanks.
Heinkel He-51 fighter
A He-51 appears in the film, used by Nationalists to bomb Madrid, almost killing Father Escrivá. The He-51 was supplied to the Nationalists very early in the war by Germany. Initially, they were flown by German pilots of the Condor Legion. As more modern planes became available to the Condor Legion, Spanish pilots took over flight duties of the He-51.
The Lancia IZ armoured car appears in the film, used by the Nationalist forces during the last battle scene. These armoured cars were operated by the Italian Forces under the Nationalist cause during the Spanish Civil War. The one used in the movie was fitted with two Maxim-derivative Machine Guns and a speaker that was used as a microphone.
