Luc Dardenne

Arta Dobroshi, Marion Cotillard and Adèle Haenel are the only non-Belgian actors that he and his brother cast to lead one of their films since Je pense à vous (1993). Cotillard was cast in Dos Dias, Una Noche (2014) after meeting the brothers on the set of Metal y hueso (2012), which was co-produced by them. The original plan was to work together in La chica desconocida (2016), which was eventually made years later with Haenel in the lead. Cotillard is the most famous actor that the Dardenne brothers have ever worked with.

That happens a lot with experienced actors. They close down and protect themselves, and then all you get are the same mannerisms, the same tricks, the same character.
