After his successful debut, Matuszyński directed a few TV series: The Pack, Druga Szansa (Second Chance, trans. NS) and Nielegalni (The Illegal, trans. NS). However, it was Król (King, trans. NS) that everybody was waiting for. The show, based on Szczepan Twardoch’s acclaimed novel (the English translation by Sean G. Bye, titled King of Warsaw, was published in 2020) premiered in November 2020. As the novel is set in the 1930s, the series posed a challenge, requiring a recreation of interwar Warsaw. As the director said in an interview with Culture.pl:
Someone once said that my film ‘The Last Family’ is an ‘epic film set in interiors’. Shooting ‘Król’, I wanted to achieve exactly the opposite. Even though the novel surely is epic and includes numerous characters, I believed that it should be an intimate story.
The series stars Michał Żurawski, Kacper Olszewski, Arkadiusz Jakubik, Borys Szyc and Magdalena Boczarska. The script was written by Łukasz M. Maciejewski, Szczepan Twardoch and Dana Łukasińska. Kacper Fertasz, Matuszyński’s long-term collaborator, was responsible for cinematography.
Matuszyński was one of the directors invited by HBO to shoot a segment for the 'At Home' anthology. The director decided to document his everyday life, recording his family waiting for the birth of a child during the uneasy times of social isolation during a pandemic.
