A new trailer and poster for the drama Sound of My Voice have gone online. The film was one of two breakout hits for star/co-writer Brit Marling at the 2011 Sundance Film Festival, the first being the sci-fi drama Another Earth. I’ve heard nothing but great things about Sound of My Voice and I was beyond intrigued by the first 12 minutes of the film that were released online. The story involves a pair of investigative journalists who infiltrate a mysterious group led by an enigmatic leader (Marling) with the intent of exposing her as a fraud. This trailer gets into the larger issues explored in the plot, and Dave remarked in his recap of the film’s WonderCon panel that the hint of menace seen in the opening 12 minutes of the film looks to escalate dramatically in this trailer. The clip is sure to draw interest and I’m incredibly eager to see the full film when it hits theaters.Hit the jump to check out the trailer and poster. Sound of My Voice opens on April 27th.Click over to Apple to watch in HD.Here’s a synopsis for Sound of My Voice:
