Paul Thomas Anderson continues to cast his adaptation of Thomas Pynchon's novel "Inherent Vice," as Martin Short and Jena Malone are the latest additions to the star-studded ensemble, TheWrap has learned.

Warner Bros. did not immediately respond to a request for comment, while a representative for Malone had no comment.

Short and Malone are expected to join Joaquin Phoenix, Owen Wilson, Benicio Del Toro and Reese Witherspoon in the soft-boiled crime film, which follows a pot-smoking private detective named Doc Sportello (Phoenix) as he investigates a missing persons case that may have larger implications.

Malone will play a former drug addict who asks Sportello for help, while Short's small role is being kept under wraps.

Warner Bros. is financing and distributing the comedic film, which Anderson is producing through his Ghoulardi Film Co. along with JoAnne Sellar and Daniel Lupi.

While it has been years since Short was last seen on the big screen, he did voice key characters in Tim Burton's "Frankenweenie" and DreamWorks Animation's "Madagascar 3: Europe's Most Wanted," and he's also set to star in the Public Theater's one-night-only performance of "The Pirates of Penzance" in Central Park. He's repped by WME and Brillstein Entertainment Partners.

Malone will soon be seen playing Johanna Mason in "The Hunger Games: Catching Fire" and she recently co-starred alongside Bill Paxton in the "Hatfields & McCoys" miniseries. She's repped by the Gersh Agency and attorney Robert S. Wallerstein.
