Laura Dern will join Reese Witherspoon in the upcoming drama, Wild.

According to Deadline, Dern will play Witherspoon’s mother in the flick, despite there being only nine years between them.

The flick is based on Cheryl Strayed’s 2012 memoir, and has been adapted for the screen by Nick Hornby.

Witherspoon will star as Cheryl, a woman still reeling from her mother’s death, drug abuse, and a failed marriage.

She decides to walk the 1000-mile Pacific Crest Trail in an effort to rediscover herself.

Jean-Marc Vallée will direct.
