For a follow-up to his 2012 film The Master, Paul Thomas Anderson has been hard at work on a film adaptation of Thomas Pynchon's 2009 novel Inherent Vice - a fairly lighthearted novel (for Pynchon, anyway) which follows the story of a detective investigation a kidnapping between 1969 and 1970. The project already boasts an impressive cast featuring Joaquin PhoenixBenicio del Toro, Owen Wilson, Jena Malone, Martin Short, and Reese Witherspoon, but, according to Grantland, it just got a little more impressive: Sean Penn is apparently in talks to take up a role in the film.

The role is unspecified, but there's speculation from Paul Thomas Anderson fansite Cigarettes & Red Vines that it will be the role of Adrian Prussia - "a powerful loan shark known to get violent when not compensated properly." Hopefully in psychedelic get-ups, because after all, it is the '60s.
