Lucy Hale is one of the many actresses on board for "Scream 4," which hits theaters on April 15.
While the "Pretty Little Liars" actress' role is unknown, she does admit that she's in the opening sequence.
"What people don't know is that we did that in one take, which is amazing," Hale told OnTheRedCarpet.com host Chris Balish at the film's premiere on April 11, 2011 in Los Angeles. "I don't even know what to say because I can't talk about it."
"I mean there's definitely a twist at the end [of the opening]," she added. "I think it starts the movie off right, it sets the tone for what you're going to see throughout the movie."
As for what the rest of the film holds, the actress says she was clueless. "I actually haven't seen it yet. I actually haven't been given the script for it because it was such a secret project," she said.
The first movie came out in 1996 and is known for the ghost mask used by the films' killers. The fourth movie is set to hit theaters on Friday, April 15 and stars original cast members Neve Campbell, Courteney Cox and her estranged husband David Arquette.
Other newcomers include Kristen Bell, Emma Roberts, Hayden Panettiere, "Mad Men" and "Community" star Alison Brie, Adam Brody of "The O.C." and Rory Culkin, brother of Macaulay Culkin.
So what makes the masked killer still scary after 15 years?
Hale says, "It's what's behind the mask because you don't know. You never know."
