“New Moon” is currently shooting in Vancouver and, as the entire cast is coming together on set, fans are eager to learn more details about what surprises are in store for them come November. Alex Meraz, cast as a wolf pack member for the sequel, is here to deliver all the goods – including details on a transformation scene that will see him without a shirt.

Meraz, well known for his martial arts skills, has opened up about what it means to share the same set with Robert Pattinson, Kristen Stewart and the rest of the “New Moon” cast and, not surprisingly, he has nothing but good things to say about them. However, the surprise “Twilight” fans will probably find the most interesting is that the film will also include a scene in which he turns into a werewolf; and it will be something else, the young actor promises.

“It’s really cold in Vancouver and, you know, I have no shirt on.” Meraz tells Access Hollywood at the premiere of “17 Again.” “[And] sometimes, not [even] shoes! I think the real acting is coming in and trying to act like I’m warm. I filmed the transformation scene, which I’m gonna say right now… it’s something else. It’s going to be something to look forward to, for sure!” the actor adds.

As for what it means to be working on the sequel of such a successful and immensely popular movie as “Twilight,” Meraz says that everybody is “good people,” and they get along just fine. Even director Chris Weitz falls in the same category, Meraz says, despite being in the habit of making jokes at his expense for having to work out every time before going in front of the camera.

“It’s been really good. The cast is just fantastic. The other guys are just really good. They’ve been pretty good. They’ve left me alone… they’re good people.” Alex says of the “New Moon” cast. “I have to work out before takes and he [Weitz] kind of comes in, and he’ll grab two dumbbells and he tries working out [with] his little frail body. I try to teach him techniques. He’s amazing! He’s so fun to work with, he’s very charismatic and he has a good time, everyone loves him.” the star adds for the same publication.

“New Moon” drops in theaters on November 20. For more details on the production that is set to be the biggest release of the year, keep an eye on this space.
