In common with other European countries, the most frequent and most popular form of theatre in Poland is dramatic theatre, based on the existence of stable artistic companies. It is above all a theatre of directors, who decide on the form of its productions and the appearance of individual scenes. There is no strict division in Poland between theatre and film directors and actors, therefore many stage artists are known to theatre goers from films of Andrzej Wajda, for example: Wojciech Pszoniak, Daniel Olbrychski, Krystyna Janda, Jerzy Radziwiłowicz, and from films of Krzysztof Kieślowski, actors such as Jerzy Stuhr, Janusz Gajos and others.
