The young man is is troubled, distant and angry, playing truant from school for months. Peter strives to be a better father, searching to help his son with those intimate and instinctive moments of family happiness. But the weight of Nicholas’ condition sets the family on a dangerous course.

The film is being produced by Oscar winners Iain Canning and Emile Sherman (“The King’s Speech”), as well as Joanna Laurie of See-Saw Films and Christophe Spadone (“The Father”) alongside Zeller. Film4 are co-financing. Shooting is expected to start in the coming weeks.

“Vanessa Kirby is for me a very great actress: intense, inventive and powerful. I am especially happy to take her on this cinematic adventure,” said Zeller.

Laurie added that the project “holds a mirror up to our families and our emotions and we’re very excited to add Vanessa to the already exceedingly talented cast of Hugh Jackman and Laura Dern in bringing this story to life.”
