The record for the longest run of a theatrical play with the same cast is for the play ‘Exercises in Style’ performed by Pero Kvrgic and Lela Margitic and directed by Tomislav Radic (all Croatia) from January 1970 to present.
The opening night of this play was on 19 January 1968, but in 1970 the leading actress role passed from Mia Oremovic to Lela Margitic. There are no exact dates of this fact but it was on January 1970. The play is currently played on the Theater Planet Art in Zagreb. All the performances, from 1968, have taken place in Zagreb.
