So it turns out that the mysterious trailer for Sigur Ros' INNI wasn't for a "concert DVD" after all, much to the joy of one infuriated commenter. Apparently, it's a "surprise film event" that will be screened at Venice Days, which is a derivative of the Venice Film Festival that begins Aug. 31. At least, that is how the folks behind Venice Days described INNI, according to the Playlist. It's pretty much still a mystery beyond that, though, except for the announcement that it was directed by Vincent Morisset. He's the same guy behind Arcade Fire's Miroir Noir documentary, which leaves us thinking this Sigur Ros film should be pretty incredible.
