Hervé-Jacques Passard is very good here

For me, Hervé-Jacques Passard's work in The Great Smog of London (2026) is easy to talk about after watching. It is not too loud, but I still remembered the performance after watching. The timing is good, and the emotion comes at the right moments. The acting feels natural, and I can follow the feeling very easily. I think this work helps the movie a lot, even when the story is busy. It is one of the reasons the movie stayed interesting for me.
