MacFarlane and Stone will unveil the nominations at a 5:30 a.m. PT news conference at the Academy's Samuel Goldwyn Theater in Beverly Hills, where hundreds of media representatives from around the world will be gathered.
Since the first nominations announcement in 1964, the Academy president has been joined by one or more co-announcers at the event. This year the Academy will break with tradition when MacFarlane, who was named Oscar show host in October, joins Stone on Oscar nominations morning. Charlton Heston (1972) was the only other show host to participate in the nominations announcement.
Stone starred in the 2011 Best Picture nominee The Help and the summer release The Amazing Spider-Man. Her other film credits include Superbad, Zombieland, Easy A and Crazy Stupid Love. Stone will be seen in Gangster Squad later this month and in The Croods, due out in March.
Nominations information for all categories will be distributed to news media in attendance and via the Internet on the official Academy Awards website, Oscar.com.
