Vivica A. Fox, Steve Guttenberg, Ryan Sypek and “Saturday Night Live” veteran Cheri Oteri have been cast opposite Jessica Simpson in the comedy Major Movie Star for Nu Image/Millennium Films. “High School Musical’s” Olesya Rulin, “Gilmore Girls” regular Keiko Agena, Jill Marie Jones, Aimee Garcia and Gary Grubbs also star in the story of Megan (Simpson), a somewhat clueless movie star who impulsively enlists in the U.S. Army Reserve after discovering her boyfriend is gay and her cousin/accountant has stolen all her money.

Fox will play Sgt. Louisa Morley, an intimidating training officer who goes hard on Megan. Guttenberg will play the controlling agent Sidney Green, furious at her for enlisting and at Gen. Greer (Grubbs) for keeping her there. Sypek will play the handsome officer Megan falls for, Sgt. Mills Evans. Oteri will play Pvt. Jeter, the most gung-ho recruit on the base and Megan’s arch-nemesis. Jones, Rulin, Agena and Garcia will play Megan’s fellow reservists.

Filming on director Steve Miner’s feature began Monday at Camp Minden near Shreveport, La. Oteri contributed recent revisions to April Blair and Holly Sorensen’s screenplay.

The producers are Bill Gerber, Joe Simpson, Randall Emmett and Denise Di Novi. The executive producers are Avi Lerner, Michael P. Flannigan, Danny Dimbort, Trevor Short, Boaz Davidson, John Thompson and Joe Gatta. Stephen Emery and Dal Walton are co-producing.
