Laura Dern is to star alongside Reese Witherspoon in upcoming drama Wild.
The Jurassic Park actress will play the mother of Reese's character in the film, reported Deadline.
The story is adapted from Cheryl Strayed's best-selling 2012 memoir and follows Reese's character, who is struggling to deal with drug use, the death of her mother years before and a failed marriage.
She decides to go for a 1,000-mile walk alone to help her face her problems and find meaning in her life.
It's thought her mum, the role 46-year-old Laura will play, could appear in flashback scenes.
Wild, which has already started shooting, is being directed by Jean-Marc Vallee.
Laura was last seen on the big screen in 2012's The Master. Her upcoming film projects include the movie adaptation of the book The Fault In Our Stars and drama film Strings.
