Birdman, Eddie Redmayne, Julianne Moore and Orange Is The New Black were the toast of the 21st annual Screen Actors Guild Awards on Sunday night (25Jan15).

Director Alejandro Gonzalez Inarritu and the cast of Birdman were given their biggest boost yet ahead of the Academy Awards after landing the Outstanding Performance by a Cast in a Motion Picture title, while the lead acting accolades were awarded to newlywed Redmayne, who was recognised by his peers for his portrayal of physicist Stephen Hawking in The Theory of Everything, and Moore, who was feted for her role as a mother battling early onset Alzheimer's disease in Still Alice.

Whiplash's J.K. Simmons and Boyhood's Patricia Arquette also continued their awards season winning streak by taking home the top supporting acting film honours.

All four actors are Oscar nominated and are favourites for the biggest night in Hollywood next month (Feb15).

Meanwhile, House of Cards' Kevin Spacey repeated his Golden Globes success by claiming the Outstanding Performance by a Male Actor in a Drama Series and Viola Davis picked up the female equivalent for her new crime drama How to Get Away with Murder.

Hit series Orange Is the New Black was a double winner, while the cast of popular British period drama Downton Abbey earned the accolade for Outstanding Performance by an Ensemble in a Drama Series.
