Mancs ("Paw", pron. "manch") was a real German Shepherd rescue dog, a contemporary hero in Hungary in the early 2000s. He saved many lives after various disasters in many countries. A bronze statue was erected to his memory in the city of Miskolc.
The former owner and trainer of the real-life Mancs and Spider Rescue Team which employed him during his life has spoken out against this movie and called for a boycott, even demonstrated at a cinema in the city of Miskolc against its premiere. As they put it, the movie "desecrates" the memory of Mancs, it's falsifying his and the team's story. According to László Lehóczky, the real-life Mancs' former owner, he was never even called by the filmmakers and they never asked for his permission to use the hero dog's name. The demonstrations caused a huge public uproar against the movie in Hungary.
Filmed in 2013, but only released after two years.
