Film and literature buffs alike can rejoice: the trailer for Paul Thomas Anderson’s adaptation of Thomas Pynchon’s Inherent Vice is here at last.

The film marks both Anderson’s seventh film and the first movie adaptation of a Pynchon novel. And judging from the trailer (above), the end result is a delightfully bonkers comedy. Starring Joaquin Phoenix, Josh Brolin, Reese Witherspoon, Benicio Del Toro, Owen Wilson and Martin Short, the film follows private investigator Doc Sportello (Phoenix) on a bizarre investigation during the “tail end of the psychedelic ’60s” in Los Angeles.

The film will make its world premiere on Oct. 4 at the New York Film Festival, before opening across the U.S. on Dec. 12.
