In the scene of the meeting in the Donuzlav lake of two resisting ships "Cherkasy" and "Genichesk", the latter was led by the real commander of "Genichesk" - Oleksandr Boychuk, who was resisting against russians in 2014. You can see him in a window of "Genichesk". But his character was played by an actor in a movie.

The director, screenwriter and author of the idea of the film comes from the city of Cherkasy in central Ukraine, after which the minesweeper U311 was named.
