After leaving the Polski Theatre, Bardini worked as the Artistic Director at the Stefan Jaracz Theatre in Łódź, the General and Artistic Director at the Ateneum Theatre in Warsaw, as well as at the Współczesny Theatre in Warsaw and again at the Polski Theatre. Since the mid-1960s he staged his guest productions at the Stary Theatre in Kraków and on the Warsaw theatre scene. Bardini’s interest lay in the older or more recent classics. At the Ateneum Theatre in Warsaw, he produced Shakespeare’s A Midsummer Night’s Dream (1959), Henry IV (1960), Measure for Measure (1965) and Henrik Ibsen’s Jan Gabriel Borkman at the Współczesny Theatre in Warsaw (1975). Bardini also directed contemporary dramas, in particular those written by American playwrights: Tennessee Williams’s A Streetcar Named Desire (Ateneum Theatre in Warsaw, 1959) and The Night of the Iguana (Polski Theatre in Warsaw, 1966), as well as Thorton Wilder’s Our Town (Theatre Academy, Warsaw, 1966). The director showed a similar repertoire at the Television Theatre. Aside from the renowned television production of Anton Chekhov’s Three Sisters (1974), Bardini directed Harold Pinter’s The Dumb Waiter (1973) and Pavel Landovsky’s Pokój na Godziny / The Hour Hotel (1989). Bardini’s theatre productions focused specifically on the acting side. Many famous actors gave excellent performances in his productions: Andrzej Łapicki and Elżbieta Barszczewska (The Night of the Iguana), Jan Świderski (Sean Ocasey’s Red Roses for Me, Dramatyczny Theatre in Warsaw, 1964), and Henryk Borowski (Pokój Na Godziny / The Hour Hotel). One of Bardini’s most outstanding theatre productions in terms of cast was Three Sisters with the participation of Bronisław Pawlik, Marek Walczewski, Jerzy Kamas, Piotr Fronczewski, Władysław Kowalski and students of the Theatre Academy in Warsaw: Ewa Ziętek, Krystyna Janda, Joanna Szczepkowska and Anna Szczepaniak.
Andrzej Wanat wrote, ‘Bardini had a talent for casting. Sometimes his choices were surprising, unconventional and definitely not stereotypical. For example, Walczewski cast as Vershini’.
