If you’re a “Heroes” fan, I’ve got a treat for you today. My guest is Cristine Rose, who stars in the NBC drama as the mysterious, calculating matriarch Angela Petrelli, who, we believe, is willing to sacrifice anything, including her gifted sons, Nathan and Peter, to change the world. Apparently, having sons played by Adrian Pasdar and Milo Ventimiglia, doesn’t have much impact on Angela! Christine, who is a commanding presence on the screen, is a veteran TV actress whose roles have included appearances on “Picket Fences,” “Providence” and “Friends.” She even has an episode of “Star Trek: The Next Generation” to her credit, playing, I believe, a Klingon. More recently, she’s been seen on episodes of “How I Met Your Mother” and “Big Love.” Cristine Rose •
