It looks like the best actress Oscar category might have to make room for two widely-revered redheads. Alice’s Julianne Moore has been its clear front-runner since her film premiered at the Toronto International Film Festival in September. Now she may be joined by the year’s most prolific actress, Jessica Chastain, as well. Chastain was being pushed for only her two supporting performances, in Christopher Nolan’s Interstellar and J.C. Chandor’s “A Most Violent Year” — which was singled out for a National Board of Review honor earlier this week. But not for her leading turns in Liv Ullmann’s “Miss Julie” or Ned Benson’s “The Disappearance of Eleanor Rigby.” The Hollywood Reporter has learned that The Weinstein Company, which acquired “Rigby” after its North American premiere at Toronto in 2013, has made an internal decision to aggressively get behind Chastain for a best actress nod — both Oscar AND Golden Globe — for her work in that independent film.
