The final paper analyses the historic development and theatrical style of the Histrion Acting Company between 1975 and today. Under the artistic and executive management of its founder Zlatko Vitez, the company went through three distinct creative stages. Created in the 1970s, along with numerous other independent theatre companies opposing the concept of institutional theatre, the Histrion Acting Company began its career as a summer touring company devoted to visiting small towns along the Adriatic coast and islands on a boat and giving productions to audiences largely unaccustomed to theatre performances. In addition to the touring company, in the 1980s Vitez also established the Zagreb Histrion Summer (1986), broadening the existing repertoire with spectacular, ensemble productions of popular Zagreb authors, such as Marija Jurić Zagorka. The productions took place during summer months and entertained the audience of Croatian capital. The third artistic stage begun in 2007 when the company obtained its permanent performance space and opened the doors of the Histrion House situated in 90 Ilica Street. From that time, the Histrion House offered daily performances during the entire season and hosted two festivals founded by Zlatko Vitez and named after well-known Histrion actors –the Gumbek’s Days cabaret festival named after the comic actor Mladen Crnobrnja Gumbek and the Bobi’s Days of Laughter named after Josip Bobi Marotti. In line with the historic overview of three different production models that enabled the company to attract new audience, the paper examines the repertoire and describes the theatrical poetics of unique histrionic and contemporary, popular and actor-based theatre focused on immediate communication with its spectators. Bringing together generations of actors and theatre artists, the paper unveils how during the 46 years of uninterrupted existence and headed by the living legend of Croatian theatre, actor and stage director Zlatko Vitez, the Histrion Acting Company successfully accomplished its cultural mission of – distributing theatre culture, generating new models of organization, asserting Croatian writers, creating recognizable theatrical style, and finally, shaping the authentic Zagreb theatre brand.
