I'm watching Call My Agent on Netflix and it reminded me of another French thing I wanted to see. Its fairly recent, maybe last 3 years?
Here is my vague description
The main character is a French actor who goes to America.
Maybe he has a long lost son there and/or he's not famous in the US but he is famous in France.
That's as much as I can remember, although in the trailer I can see him getting in or out of a car out side a building.
I said it was vague!
Thank you!!
