On third ballot, "Moneyball." Runner-up is "Margaret." A motion was passed to issue a statement criticising Fox Searchlight for offering no screeners for "Margaret" and screening it for members days before the meeting. Despite this it has gotten numerous votes in various categories suggesting that had more members been able to see it it might have won some of these awards.
Second round, "Carnage," followed by "Margeret."
After three tough rounds, it's Melissa McCarthy in "Bridesmaids." A close runner-up was Jeannie Berlin in "Margaret."
