Yet beyond these glittering powerhouses lies a vibrant ecosystem of smaller, specialized festivals where daring storytellers, emerging voices, and boundary-pushing formats find passionate audiences and industry champions.

Here are ten international film festivals you’ll want on your radar for 2025.
