The biographical documentary Lone Wolf (Osamělý vlk) is slated to arrive in Czech cinemas on August 27, 2026, according to production details released by the Czech Film Center. Directed as a documentary debut, the 85-minute film chronicles the life of Josef František, recognized as the top-scoring Czechoslovak fighter pilot during the Battle of Britain.
Following Josef František From Exile to the RAF
According to the Czech Film Center, the documentary traces František’s departure from his Nazi-occupied homeland through Poland and France before reaching Britain. Determined to return to active combat, he joined the Royal Air Force’s legendary No. 303 Polish Fighter Squadron. The production captures how his exceptional flying talent and combat instincts quickly established him as the most successful foreign fighter pilot of the campaign.
Production Background and Creative Team
The film is an 85-minute documentary co-produced in the Czech Republic and Poland, featuring dialogue in Czech, German, English, French, and Polish according to the Czech Film Center. The project lists Kryštof Tichý as director of photography, with Ondřej Veverka and Petr Pelech credited as writers. Postproduction work is scheduled for completion in August 2026 ahead of the late-summer theatrical release.

Balancing Heroism and Military Discipline
The narrative explores the friction between František’s combat achievements and his independent approach to military structure. According to documentation from the Czech Film Center, his untamed nature set him apart in the skies but frequently brought him into conflict with ground discipline and direct orders. As his victory tally climbed, the documentary illustrates how the pilot earned a reputation as a solitary figure within the allied ranks.
