According to The Hollywood Reporter, Vince Vaughn and Catherine Keener have boarded the Sean Penn-helmed Into the Wild, which Paramount Pictures' new specialty division is distributing.

Emile Hirsch already has signed on to star in the film, which chronicles the true story of Christopher McCandless, who graduated from college in 1992, abandoned his possessions and hitchhiked to Alaska to live in the wilderness and return to nature.

He died four months later in an abandoned bus at a remote campsite.

Penn adapted the screenplay from Jon Krakauer's book of the same name. Keener's character picks up the hitchhiker and takes him in as a surrogate son. Vaughn plays a tow-truck driver whom Hirsch's character meets on the road.
