After a period of dictated and controlled dramaturgical uniformity, which marked all theaters established after 1948, artistically remarkable, more poetic productions by the director and artistic director of the theater, Jozef Palka, also appear in the Žilina theater. As the thyrologist Ján Jaborník states in a study of Žilina's professional theater: "Against the superiority of the model of realistic play of the 19th century and especially against expressionlessness, propagandistic ideology, naturalism and descriptiveness, Palek's work posed artistic sophistication more rebellious poetry. " In the all-Slovak premiere, for example, Jozef Palka presented the impressionist story of Šrámek's Leto (1956), where Hana Čelková - Hegerová also played one of the main roles. It was the only Slovak study so far. During this period, the legendary, most spectator-successful production of Hviezdoslav's Hájnik's Wife (1955) in Palkov was directed by the Žilina theater. Palko's work in the Žilina Theater, which is one of the most artistically successful periods in the Žilina Theater, culminated artistically with the introduction of the nationwide premiere of the production of Schiller's drama Mária Stuartová (1957) starring Bohumila Horňáková - Růžičková.
