Don’t be afraid (1981)

Nebojsa was the nickname given to a young man who was not afraid of anything. One day he heard that a cursed princess lived in a castle. Whoever could uncurse her would have her as his wife and half the kingdom. Dear Nebojsa went out into the world to try his luck. He experienced many adventures until he reached the goal of his journey. But the greatest danger awaited him in the mysterious castle. If he wanted to uncurse the princess, he had to fulfill a difficult condition: no matter what evil was done around him and to him, he was not allowed to reveal, even with a word, that he was afraid. Well, he certainly wouldn't be Nebojsa if he didn't fulfill this task. And so he won the princess and the kingdom.
