How old were the actors in Resina (2018)?

Maria is a young cellist who, disappointed by the world of musicians, returns to her mountain village where a forgotten language is spoken: Cimbrian. However, her family's situation is not easy and life in the village is monotonous. With one exception: the choir, which in the past enjoyed great recognition but now has a skeleton staff. The elderly Quirino tries to do what he can, but with little success. Maria could be of great help, if she wanted to.
