MONTREAL - Christopher Heyerdahl has one more bit of insight as he closes out his role as Marcus, one of the overseers of the vampire world in the mega-popular "Twilight" movies.
But he's only giving a nibble as fans line up for "The Twilight Saga: Breaking Dawn Part 2," the final chapter in the series which opens on Friday.
"There's a part in the film ... that's not in the books," he said. "And it's in a way a gift to the fans, something that they will not expect, something they won't have already imagined in their heads and their expectations aren't there. It will be a complete surprise."
And the reaction of the fans at the recent Los Angeles premiere? A good payoff?
"They went absolutely nuts," he said.
"It was like the final movement of a major opus and it was amazing to listen to. The final movement is very delicate and very celebratory of the whole series itself. It's a great finish to the series, it's something that we all feel very proud of."
Heyerdahl, who has been in three of the "Twilight" films — "New Moon" and the two "Breaking Dawn" instalments, reprises his role of Marcus, a member of the Volturi, in the new film. The Volturi are basically the overseers of the vampire world and do whatever it takes to keep their fanged charges in line.
The Vancouver actor is a little wistful about bidding farewell to his bloodsucking alter-ego.
"I loved playing the part so yeah, sure, I'll miss Marcus," the lanky actor said in an interview in Montreal.
"I always have a soft spot for any character that I put my heart and soul into and try to create something that's three-dimensional and has a history and a present and a future — even though Marcus may not necessarily want to have a future."
In "The Twilight Saga: Breaking Dawn Part 2," the Volturi are grappling with the appearance of an immortal infant who brings a new definition to the "terrible twos" phase of childhood. When this kid throws a tantrum, thousands die.
"It doesn't work out well for the Volturi," Heyerdahl explained, noting that having immortal children is a violation of Volturi law.
This all sets the stage for an all-out battle fit to bring the franchise to an epic climax.
In the films, Marcus has offered a contrast to his more ruthless brothers Aro and Caius. He mourns the loss of the love of his life in a battle 2,500 years ago and Heyerdahl says he is actually touched by seeing hero and heroine Edward and Bella and the passion they share.
"He relates to that. It brings him back to the old days. At the same time, I'm sure it makes him pine much more for his love," says the actor, who is also currently appearing in TV's "Hell On Wheels."
"He really is the balance in this triumvirate of power," Heyerdahl says of Marcus. "He tries to be the voice of reason and I found that extremely interesting to play."
Heyerdahl says there is a moment in the new movie that promises to bring some salve to Marcus' pain and that pleased him.
"It's a fantastic moment," said the actor who has a slew of credits to his name, including appearances in TV's "True Blood," "Supernatural" and "Sanctuary."
Heyerdahl says there wasn't much melancholy as the production of "Breaking Dawn Part 2" neared completion.
"It was actually a bit of a celebration," he said, noting that "Twilight" came to the screen with a huge fan following from the book series and high expectations. Not everyone was pleased at first, he added, but fans eventually embraced the interpretation.
"I think it's a feeling of accomplishment," he said of the final view of the cast.
Heyerdahl said it's always amazing when something becomes a phenomenon and it's nice to be part of it because it's rare. He expressed admiration for how the young stars who "got thrown into the lion's den of fame" handled their worldwide recognition.
"It cannot be an easy thing to go from one day being just a regular working actor to the next day being obsessed over worldwide," said Heyerdahl, who has performed at the Stratford Festival.
"I think they've dealt with it as well as anyone possibly could. That's a wonderful thing to witness."
