Cast to portray Marcus, one of the Volturi leaders in "The Twilight Saga's New Moon", Canadian actor Christopher Heyerdahl speaks up about what he knows of the thousands-year-old vampire. In an interview with Sci Fi Wire, the Alastair depicter in The CW's "Supernatural" reveals that his character "is a 3,000-odd-years-old vampire who has spent at least the last 2,000 of it with a broken heart."

Confessing that he took the role for his niece, Heyerdahl continues to explain more about Marcus. [Possible Spoilers Ahead] "Here's how I approach him," he begins. "When Marcus is brought in, he's there against his will. He and his love tried to leave an awfully long time ago. Through a series of tragic circumstances, the love of his life was killed, and he's now being forced to stay and use his powers for the betterment of the Volturi."

"He's not exactly there, waking up and looking forward to eternity. When Edward and Bella come walking in, his ability to sense the power of their connection is something that wakes him up, brings him back from the boredom of that eternal life and sparks something in him that brings Marcus as close to excitement as he can get."

"That idea has to be contained and expressed as little as possible to his rather power-hungry captain-in-arms, Aro, which makes for a rather interesting conflict. You might not know it, but Marcus is pretty darn excited by this love that he witnesses. At the same time, it causes him great pain with the memory of what he had and lost. It was very complex to play, especially when you are doing it with so few lines. It will be interesting to see how it is cut together."

Beside talking about the character, Heyerdahl also recalls working together with Michael Sheen, saying "We had so much fun goofing off together. It was an absolute hoot." He also uses the interview to praise director Chris Weitz. "Director Chris Weitz's version for this piece is like a Renaissance painting," he says. "The images were absolutely beautiful, and the character is such a tragic old fellow."

A sequel to highly-popular movie "Twilight", "The Twilight Saga's New Moon" is based on the second book by Stephenie Meyer and will hit the U.S. theaters on November 20. Robert Pattinson, Kristen Stewart and Taylor Lautner reprise their roles as Edward, Bella and Jacob.
