When last seen, Michael Cera was impaled on a lamppost like a hunk of wriggling bait in “This Is the End.” In his new film he wanders the desert hugging a giant, phallic, hallucinogenic cactus. In short, he has transformed himself from one of the most irritating actors of his generation to one of the best. And a good part of the credit goes to Chilean director Sebastián Silva and his “Crystal Fairy,” a wry, sad, latter-day “Easy Rider” (1969).
Cera plays an obnoxious, naive American who has traveled to Chile in search of cheap thrills, specifically a taste of the magic cactus that he hopes will blow his mind. He enlists three friends (played by Silva’s brothers) to help him on his quest. Full story for BostonGlobe.com subscribers.
