Filming is underway on Paul Thomas Anderson's Inherent Vice, and the first set photos have arrived online. Based on the book by Thomas Pynchon, the story takes place in 1969 Los Angeles, and centers on a pothead/private detective Larry "Doc" Sportello, who is helping a former lover with an intriguing case that involves infidelity, mental institutions, and policemen called "Bigfoot." As you can see, Joaquin Phoenix is rocking the muttonchops as Sportello, and the set photos also reveal that a very pregnant Maya Rudolph has a part in the movie. She joins a cast that also includes Katherine Waterston, Josh Brolin, Benicio Del Toro, Owen Wilson, Reese Witherspoon, Martin Short, Jena Malone, Kevin J. O'Connor, and possibly Sean Penn.
