Sean both directs and stars in the film, with daughter Dylan and son Hopper, 27, playing his character’s kids. The actor shares his two adult children with ex-wifeRobin Wright, from whom he divorced in 2010.
At a Cannes press conference last month, producer William Horberg said it was a dream come true to have the Penns join theFlag Daycast,IndieWire reported.
“When I dreamed from the beginning to make the movie with Sean Penn as John Vogel, to have a real father and daughter play a father and daughter, knowing Sean’s commitment to authenticity, this was a special way for this story to be told,” Horberg said. “We didn’t compromise. We had to fight hard to get the resources, to get Sean to do this.”

“For me, it was equal to doing family therapy in a room full of strangers,” the actress said, adding “I’ve done family therapy, but I’ve never done it with a crew that I didn’t know.”
In fact, Dylan said that Wright encouraged her to take the role with Sean behind the camera from the start.
“She very simply said, ‘I’ve never worked with a better director than your dad. It was the most amazing experience I’ve ever had as an actor,'” Dylan told PEOPLE of her mother’s advice. “So I trusted that.”
In the same conversation, Sean celebrated his daughter’s work onscreen.
“There were times that I had to not only avoid going in to hug her but, in fact, push for more,” he told PEOPLE of production, joking “I felt like somebody ought to call Child Protective Services at that point.”
