During the shooting of this film, Hugh Jackman's father passed away.
Based on the play with the same name by Florian Zeller, who is the director of this film. The play was set in Paris, but the movie is set in New York City, even though it's mostly filmed in London.
Second collaboration of Anthony Hopkins and Florian Zeller after the movie The Father (2020). Hopkins' role doesn't exist in the play, it was added specifically for him, to add an extra layer to Hugh Jackman's role.
The French intern at Peter's office, played by Gabriel Ecoffey, is Zeller's step-son, whose issues partly inspired the stage production of the play.
The cast includes two Oscar winners: Laura Dern, Anthony Hopkins, and two nominees: Hugh Jackman, and Vanessa Kirby.
