“Young Adult” star Charlize Theron has parted ways with her longtime manager J.J. Harris of One Talent Management.Sources close to the situation told Variety that there was no acrimony — the working relationship had simply run its course. “We had a great run, but Charlize is booked for the next couple years and simply doesn’t need a manager right now,” Harris told Variety. “She wants to focus on her production company. We remain friends.” Harris signed Theron in the mid-90s when she was an agent at UTA and the South African thesp spilled a Diet Coke on her in a meeting. It wasn’t long before Theron booked a key role in the MGM thriller “2 Days in the Valley,” which featured her front and center in the film’s ad campaign. Harris continues to manage Dakota and Elle Fanning, who’s coming off films directed by J.J. Abrams, Francis Ford Coppola and Cameron Crowe, and is now in negotiations to join Angelina Jolie in Disney’s “Maleficent.” The elder Fanning has several indie pics in the can, and will next be seen in “The Twilight Saga: Breaking Dawn — Part 2.” Harris also reps Kevin Costner, who recently wrapped the role of Jonathan Kent in Zack Snyder’s Superman pic “Man of Steel.” One Talent, which recently opened an office in Sydney, is also developing new clients, including Aussie imports Celia Massingham, who was recently cast on the CW’s “Hunger Games”-esque pilot “The Selection,” and Cameron Welsh, the longtime showrunner of Oz’s star-making series “Home and Away.” Theron has a busy year ahead of her, with starring roles in two summer tentpoles — Rupert Sanders’ “Snow White and the Huntsman” and Ridley Scott’s “Prometheus,” which 20th Century Fox will release June 8, one week after Universal opens “Snow White.” She’s also skedded to star in George Miller’s Mad Max reboot “Fury Road.” Theron remains repped by WME for features.
