Viggo Mortensen is to star in comedy drama Captain Fantastic.
The Lord Of The Rings star will play a father-of-six, who teaches his children how to survive in the wilderness - but he struggles to adjust himself when he is forced out of the forests into the real world.
Steve Zahn, Katheryn Hahn, Missi Pyle and Erin Moriarty will join Viggo and Frank Langella in the film, to be directed by Matt Ross, reported Entertainment Weekly.
Harold van Lier, president of Entertainment One Films International, said: "This is a project we all fell in love with and was voted best script of 2014 by our distribution teams on the ground.
"It is a very original story, both funny and deeply emotional and a wonderful role for Viggo. I don't think we have read anything like it since Little Miss Sunshine, but this is altogether very different," he added.
Viggo, last seen in The Two Faces Of January, will next star in Lisando Alonso's drama Jauja and French drama Far From Men.
