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 I'm Thinking of You (1992). Cotillard was cast in Two Days, One Night (2014) after meeting the brothers on the set of Rust and Bone (2012), which was co-produced by them. The original plan was to work together in The Unknown Girl (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.
