Ronda Rousey signed with the William Morris Endeavor talent agency earlier this year, and now she has her first major movie role. The UFC’s women’s bantamweight champion has landed a role in the upcoming “Expendables 3″ action flick. Screenplay writer and star Sylvester Stallone announced the news late Tuesday on his official Twitter account. Rousey (7-0 MMA, 1-0 UFC) is coming off yet another first-round armbar victory. She stopped Liz Carmouche in February in the main event of UFC 157, the first women’s fight in UFC history. She currently is taping Season 18 of “The Ultimate Fighter,” which she’ll coach opposite her fiercest rival, Miesha Tate . The two then will meet in a rematch for Rousey’s title at UFC 168 in December in Las Vegas. It is unknown when Rousey’s work on “Expendables 3″ will begin or how extensive a role she will have in the film, which also stars Arnold Schwarzenegger, Bruce Willis, Jason Statham, Jackie Chan, Dolph Lundgren, Steven Seagal and former UFC heavyweight champion Randy Couture – essentially a who’s who of Hollywood action stars.
