Meraz and his wife, Kim (who have a 19-month-old son, Somak), arrive at the premiere at the Village and Bruin Theaters in Westwood, Los Angeles. "In the limo about to pass out with nerves!!" he posted on Twitter before stepping foot on the red carpet.
He may spar with Taylor Lautner onscreen, but off, they're all about the brotherhood of the Quileute wolf pack. "Werewolves represent a raw, animalistic side of sex," Meraz told PEOPLE. "Vampires are pasty; I'd rather be a werewolf."
Following the screening, Meraz hangs with an on-screen foe, vampire Alice – a.k.a., Ashley Greene – at L.A.'s Hammer Museum for the official New Moon afterparty. "It's a whirlwind," Greene told PEOPLE. "It's a momentous time in my life."
