Los Angeles - Hollywood's top actors will honour their own Sunday at the 23rd Screen Actors Guild (SAG) Awards, where Emma Stone, Casey Affleck and the cast of "Moonlight" are favoured to bring home the year's top acting prizes.

The awards ceremony at Los Angeles' Shrine Auditorium is expected to draw some of the industry's biggest stars, among them best lead-acting nominees Affleck ("Manchester By The Sea"), Stone ("La La Land"), and Denzel Washington ("Fences"), and presenters including Riz Ahmed, Viola Davis, Salma Hayek, John Legend and Dolly Parton.

Affleck and Washington are up against Viggo Mortensen ("Captain Fantastic"), Andrew Garfield ("Hacksaw Ridge") and Ryan Gosling ("La La Land") for the best leading male actor award.

Stone will face off with Amy Adams ("Arrival"), Emily Blunt ("The Girl on the Train"), Natalie Portman ("Jackie"), and Meryl Streep ("Florence Foster Jenkins") for best leading female actor.

Nominees for the best cast in a motion picture prize - SAG's equivalent to the best picture Oscar - are the casts of "Captain Fantastic," "Fences," "Hidden Figures," "Manchester by the Sea" and "Moonlight."

The cast and crew of Moonlight: Andre Holland, Ashton Sanders, Mahershala Ali, Alex Hibbert, Tarell McCraney, Naomie Harris, Trevante Rhodes and director Barry Jenkins.

Television nominees include cast members from "Game of Thrones," "Downton Abbey," and "Westworld."

Lily Tomlin is to be presented with the guild's lifetime achievement award.

The Screen Actors Guild Awards are the only televised awards ceremony to honour actors exclusively, with prizes presented in 13 categories in film and television.

The best lead acting prizes are considered strong indicators of the Academy Awards for best actor and actress.

A live web broadcast of arrivals on the red carpet begins at 2:30 pm (22.30 GMT). The awards ceremony broadcast begins at 5 pm.
