While the film is a significant piece of history, there doesn't seem to be any readily available information online about the cast. This is likely because the film was produced in Yugoslavia and there is less readily available information about it in English.
To find out the actors and actresses, you might try:
* Searching for the film's credits in Serbian language sources: If you know Serbian or can use a translation tool, you can search for information on Yugoslav film websites or databases.
* Contacting film archives or institutions in Serbia: Film archives or institutions in Serbia might have access to information about the film's cast.
* Looking for reviews or articles about the film: Sometimes reviews or articles about the film might list the cast members.
I hope this helps in your search!
