A new Czech film about one of the country’s most celebrated World War II pilots will arrive in cinemas next weekend, when Lone Wolf (Osamělý vlk) opens nationwide on Aug. 27. Directed by Ondřej Veverka, the 96-minute docudrama recounts the life and wartime career of Josef František, a Czechoslovak fighter pilot who became one of the most successful Allied aces of the Battle of Britain before his death at the age of 26.
The film combines newly shot dramatized scenes with approximately 15 minutes of period footage sourced from 10 archives across Europe and the United States. The unusual hybrid format grew out of the filmmakers’ original plan to make a documentary about František. The limited amount of surviving archival material directly connected to the pilot ultimately led them toward a dramatic reconstruction supplemented by historical footage.
Lone Wolf had its world premiere in Prostějov on Aug. 20, exactly one year after the production began filming. The project was shot in Prague, Poland and the Ostrava region, with its final days of production taking place at Prague’s Kbely military airfield in September 2025.
From documentary to historical docudrama
František left Czechoslovakia following the German occupation and joined the fight against Nazi Germany in Poland. After the fall of Poland, he continued through France before reaching Britain, where he became a member of No. 303 Polish Fighter Squadron of the Royal Air Force.
During the Battle of Britain, František established himself as an exceptionally successful fighter pilot. He was credited with 17 confirmed victories during a 28-day period, but his combat style was as distinctive as his results. He was known for breaking away from formations and pursuing enemy aircraft independently, behavior that contributed to his reputation as a pilot who did not always conform to military discipline.
That unconventional character inspired the film’s title, which refers to František’s nickname, Lone Wolf. But Veverka’s film is less interested in presenting him simply as a wartime action hero than in reconstructing the young pilot’s personal experience.
Tadeáš Moravec plays František, whose story is presented through a first-person narrative exploring not only his military career but also his emotions and personal ambitions. The cast also includes Viktor Zavadil as fellow pilot Josef Balejka, alongside Josef Trojan, Kryštof Grygar, Jan Nedbal, Jan Budař, Miroslav Hanuš and Polish actor Piotr Trojan.
The film’s narrative eventually shifts from František to Balejka, who reads from his own diaries about the gradual loss of members of a close group of Czechoslovak airmen. The group, described as a “Czechoslovak four-leaf clover,” consisted of František, Balejka, Matěj Pavlovič and Wilhelm Kosarz. Balejka was the only member of the group to survive the end of World War II. He died in Valašské Klobouky in 2004 at the age of 87.
The archival material is intended to provide historical context without interrupting the dramatized narrative. According to Veverka, the roughly 15 minutes of footage were collected from 10 archival institutions in Europe and the United States, including material he describes as particularly rare.
The production itself was comparatively compact. Veverka said the entire project was filmed over 10 shooting days, including three days devoted to cockpit scenes. The remaining dramatic material was filmed over approximately one week in locations in Poland, Prague and the Ostrava region.
Real aircraft and recreated Battle of Britain
The aerial sequences represent another major element of Lone Wolf, combining practical photography, historic aircraft and visual effects to recreate the environment in which František fought.
During the Prague shoot, Kbely military airfield was transformed to represent wartime RAF facilities, including Northolt, where František was stationed. The production also secured access to a Hawker Hurricane, the type of fighter František flew during the Battle of Britain.
According to Veverka, only around 14 Hurricanes remain airworthy worldwide. The production additionally worked with other historic aircraft, including a 1920s biplane, with further aerial combat sequences expanded through computer-generated imagery.
The approach allows the film to move between historical footage and contemporary dramatization while maintaining the momentum of a feature narrative. Period images establish the reality of the events, while the fictionalized sequences give the story access to František’s personal experiences and relationships.
New research into the pilot’s final flight also forms part of the film’s release. Independent researcher Marek Žatkovič has identified archival documents that offer a different account of František’s final hours on Oct. 8, 1940.
According to the research presented with the film, František was not on a training flight or engaged in combat with the Luftwaffe when he died. He had taken part in an operational patrol with the other pilots of 303 Squadron over southeast England. The unit encountered no enemy aircraft, and on the return to Northolt, František’s Hurricane separated from the formation.
He subsequently attempted an emergency landing near Ewell, south of London. A record from the 460th Searchlight Battery reportedly indicates that František survived the crash but died while being transported to hospital. The precise reason he separated from the formation and why he was forced to land remains unclear.
For Czech cinema, the film arrives 25 years after Jan Svěrák’s Dark Blue World (Tmavomodrý svět), which introduced a fictionalized generation of Czechoslovak RAF pilots to a broad audience. Lone Wolf takes a different approach by focusing on a documented historical figure while incorporating documentary footage and archival research into its dramatic structure.
Producer Vítězslav Jandák said the filmmakers hope to eventually present the film beyond the Czech market to audiences elsewhere in Europe. Rather than limiting the story to military aviation, the production frames František’s experience within a broader story about friendship, sacrifice and the fate of Czechoslovak servicemen during World War II.
Lone Wolf had its world premiere in Prostějov on Aug. 20 and will receive a Prague premiere on Aug. 25. The film enters regular Czech theatrical distribution on Aug. 27. A television premiere is scheduled for Oct. 28, Czech Independence Day.
