It's official! Julianne Hough will kick off her Sunday shoes and cut loose as Ariel Moore in the big screen remake of 'Footloose' -- as long as her busy schedule permits, that is.

Variety reports that Julianne's first major film role is still "contingent on working out scheduling," but shooting is set to begin in March 2010. Variety also says fans of the 1984 film starring Kevin Bacon can expect "a more mature version than the original."

Julianne's audition last month was praised by the film's director Kenny Ortega, who gushed, "She was beautiful ... so talented." 'Gossip Girl' star Chace Crawford (a.k.a. PEOPLE Magazine's Hottest Bachelor of 2009) signed on to do the film last month, after 'High School Musical' star Zac Efron turned down the role.

By the way, this won't be Julianne's big-screen debut. In 2001, she appeared -- uncredited -- as a 'Hogwart's Schoolgirl' in 'Harry Potter and the Sorcerer's Stone.'
