You could see her only in the Old Timers’ Cabaret; Jeremi Przybora and Jerzy Wasowski threatened that no more cabarets would be produced without Kalina.
The film industry had become interested in Jędrusik in 1957. She made her debut in Tadeusz Chmielewski’s film, Ewa Chce Spać (Eve Wants to Sleep). She played the small, lively part of a resident in a workers’ hostel. Jędrusik showed extraordinary talent as a comedy actress which, sadly, directors utilised only in a couple of films. She played Kazimiera Paluch – Fatima – in the episode Uprzejmy Morderca (2) (The Polite Murderer) (2) in Stanisław Bareja’s series Kapitan Sowa na Tropie (Kapitan Sowa Is onto Something) (1962). Her role as Zuzanna in Upał (Heat), a film directed by Kazimierz Kutz and based on Jeremi Przybora’s script (1964), was performed with subtlety and humour. She made a self-parody in Jerzy Gruza’s Dzięcioł (The Woodpecker) (1970).
Her best and most captivating comedy role was that of Joanna in Jan Batory’s Lekarstwo na Miłość (A Cure for Love) (1965), where she performed the part of a girl in love who, by an unfortunate twist of fate, becomes entangled in a crime story. Jędrusik portrayed the character with natural and sincere humour, filled with youthful energy and expression.
In her TV Theatre work, Jędrusik starred as Renée in Jezioro Bodeńskie (Lake Constance), and as Zita in Podróż (The Journey), directed by Stanisław Wohl, in 1959. In Jerzy Gruza’s The Ides of March (1962), she played Cleopatra, then played Helena in Piękna Helena (Beautiful Helena) (1965) and Gwendolen Fairfax in The Importance of Being Earnest (1968). In the play Łokietek, czyli Mazurek Dąbrowskiego (Elbow-High or Dąbrowski’s Mazurka), directed by Jan Kulma in 1976, Jędrusik played both Dezyderia, the queen of San Domingo, and Catherine the Great.
Jędrusik’s TV Theatre roles included Polly in The Threepenny Opera directed by Konrad Swinarski (1958), Eleonore in The Italian Straw Hat directed by Andrzej Łapicki (1962), Dorine in Tartuffe (1962) directed by Tadeusz Byrski, Laura in Indyk (The Turkey) directed by Jerzy Goliński (1964), and Lidka in Lydia Ate the Apple (1964) directed by Jerzy Markuszewski.
In the 1970s, Jędrusik performed the part of Duchess Caroline Borescu in The Lenoir Archipelago (1970) directed by Edward Dziewoński, as well as Pulcheria in Dom Otwarty (The Open House) (1977) directed by Józef Słotwiński.
