Kate Winslet’s directional debut

The project also marks a reunion between Kate Winslet and producer Kate Solomon, who previously worked together on Lee.

The screenplay was written by Winslet’s son Joe Anders, 21. Speaking to Deadline, Kate admitted that the thought of handing the film to another director felt “like I’d been stabbed in the gut.”

She told her son: “As soon as we give this to another director, it becomes theirs… I want us to really feel like we’ve done this. I want to direct it.”
