Actor Michael Cera poses for a portrait during the 2013 Sundance Film Festival, Jan. 18, 2013, in Park City, Utah.
Cera ("Juno") stars in "Crystal Fairy" as an overbearing American traveling with three Chilean brothers (Silva's own siblings, Juan Andres, Jose Miguel and Augustin Silva) a road trip through the Chilean desert in search of the San Pedro cactus for its hallucinogenic effects. Cera said he and his castmates boiled a cactus and drank the noxious brew to get a sense of what their characters were supposed to experience on a mescaline trip, but nothing happened.
"It didn't work," Cera said. "We had this plan to do it and not film because that was going to be overwhelming for everyone. We ended up drinking it and shooting that day, and everyone was fine and nobody felt anything. & Maybe we got the wrong cactus."
