Tom Wolfe’s 1968 novel The Electric Kool-Aid Acid Test is making its way to the big-screen, as Fox Searchlight has picked up the film adaptation rights to it.

The book followed Wolfe’s account of author Ken Kesey and a group dubbed the Merry Pranksters as they drove across the country in a DayGlo-painted school bus dubbed Furthur. They then use LSD and other psychedelic drugs to have personal and collective revelations.

Director Gus Van Sant and writer Dustin Lance Black are set to reunite on the project after Milk.
