Viggo Mortensen is tipped for the lead role in Captain Fantastic.
The Lord Of The Rings actor is currently in negotiations about starring in the movie, which is about a dad trying to adapt to normal life after he and his children spent years living off the grid in the woods.
Writer and director Matt Ross told Deadline that getting Viggo on board is a dream come true.
"Viggo Mortensen's dedication to his craft and to the world of the story he's telling have been an inspiration to me for years," he said.
"There is a depth to his art that I greatly admire. Any film he's in is a film I want to see. He's one of the greats.
"Getting to collaborate with him on Captain Fantastic is quite literally the best thing that's happened to me since my wife asked me to marry her."
