Taking risks has never intimidated Mark and Jay Duplass.
Since debuting at Sundance in 2003 with This Is John, an eight-minute short shot on a three-dollar budget, the New Orleans-born brothers have gained fame (but not always fortune) as the founders of mumblecore, a verité-style approach to filmmaking that favors improvisation over scripted drama. So perhaps it should come as no surprise that they took an equally fearless approach in casting Cyrus, their first studio film, which opens Friday.
