Sucker Punch starlet Jamie Chung and Twilight babe Christian Serratos have boarded Japanese director Takashi Shimizu’s (The Grudge) in-flight frightener 7500. They join Amy Smart, Leslie Bibb, Scout Taylor-Compton, Nicky Whelan, and Ryan Kwanten in the CBS Films production set to shoot this month.

Written by “LOST” scribe Craig Rosenberg, the film follows a group of apparently very attractive passengers terrorized by an evil force after the mysterious death of a passenger on Vista Pacific Flight 7500. Chung will play a newly engaged flight attendant on her maiden voyage.

Chung’s genre creds include the 2009 remake Sorority Row, Dragonball Evolution (based on the Japanese Dragon Ball magna), and the indie-anthology Burning Palms. She will next be seen as a prisoner-prostitute in the abduction drama Eden.

Christian Serratos

Serratos’ role in 7500 is a little more vague, described only as a “woman who shares a secret with her boyfriend.” Aside from showing her ass for PETA, the 21-year-old stunner hasn’t done much outside of starring in Summit’s stupidly successful Twilight Saga. She’ll be seen this month in Breaking Dawn: Part One.

7500 is slated for release on Aug. 31, 2012.
