Reese Witherspoon and Jena Malone Join Paul Thomas Anderson’s ‘Inherent Vice’

It looks like Reese Witherspoon is quite eager to reunite with her Walk the Line crew. The Oscar winner recently signed on to star in Walk the Line director James Mangold’s memoir adaptation Three Little Words, and now she’s joining Joaquin Phoenix in writer/director Paul Thomas Anderson’s adaptation of the Thomas Pychon novel Inherent Vice. Set in 1970 Los Angeles, the film follows a pot-smoking private investigator (Phoenix) as he investigates the alleged kidnapping of a woman he used to date. Deadline reports Witherspoon’s casting, but has no details regarding her role in the film.

Witherspoon is just the latest A-lister to sign on to Anderson’s The Master follow-up, as the filmmaker is assembling a stellar ensemble that thus far includes Benicio Del Toro and Owen Wilson. As production is gearing up to begin soon, expect to hear more casting news in the coming weeks. [Update: The Wrap adds two new cast members. Jena Malone is expected to play a former drug addict who asks Phoenix's private eye for help—Martin Short has been cast in an unspecified role.]
