Star Wars director J.J. Abrams and his Star Trek leading man Chris Pine will join filmmaker Alfonso Cuaron for a Oscars nominations marathon on Thursday (15Jan15).

Abrams and Cuaron will announce the first group of nominees in the categories of animated feature film, documentary feature, documentary short subject, film editing, original song, production design, animated short film, sound editing, sound mixing and visual effects at 5.30am local time in Los Angeles and then Pine and Academy president Cheryl Boone Isaacs will reveal the rest of the categories.

The announcements will take place at the Academy’s Samuel Goldwyn Theater in Beverly Hills and will mark the first time all the nominations have been released at once.

In past years, the nominations unveiling has consisted of just one announcement, focusing on the top categories.

Boone Isaacs says, "This new approach enables the Academy to further recognize excellence across our entire industry and underscore the full spectrum of the arts and sciences of motion pictures."
