Repeat champs, Idris Elba and Spotlight were the big winners at Saturday's Screen Actors Guild Awards, while Leonardo DiCaprio continued his long march towards Oscar.

Ever the creatures of habit, SAG voters awarded five of the six reigning TV champions again. The Orange Is the New Black cast and Uzo Aduba claimed comedy ensemble and comedy actress for the second straight year. The Netflix series, which boasts a cast of 34, is the fourth show to win the category twice after Desperate Housewives, The Office and Sex and the City.

The cast of Downton Abbey won their third drama ensemble award overall, putting them one shy of ER's record four. Drama actor champ Kevin Spacey (House of Cards) became the eighth person to win his category twice, while Viola Davis (How to Get Away with Murder) joins Allison Janney and Gillian Anderson as two-time drama actress winners.

The only series category to see a new winner was comedy actor. After Transparent was snubbed completely last year, Jeffrey Tambor took home comedy actor honors to complete his awards collection for playing Maura Pfefferman. He is the 21st person to win an Emmy, Golden Globe and SAG for the same performance.

Elba went two-for-two with his individual nominations, winning TV movie/miniseries actor for Luther and film supporting actor for Beasts of No Nation. He is now the first SAG winner to not have a corresponding Oscar nomination. Voting for the SAG winners concluded Friday, in the midst of the #OscarsSoWhite controversy, so perhaps SAG was sending a message to the Academy. Elba had one too: "Welcome to diverse TV," he later said while presenting.

SAG Awards: The best dressed stars

Elsewhere on the film side, DiCaprio won his first SAG trophy for lead actor in The Revenant. He shouldn't have to sweat too much over the next month: 17 of the 21 SAG lead actor winners have gone on to win the Oscar, including the last 11.

After losing the Producers Guild Award to The Big Short last week, Spotlight rebounded -- and kept the Oscar race interesting -- by winning best ensemble, which, since it honors acting, has only matched the Oscar top prize 10 of 20 times.

Lead actress went to Brie Larson (Room), who looks bound for an Oscar too, as the SAG lead actress winner has matched with the Oscars 15 of 21 times.

SAG Awards: The worst dressed stars

Globe champ Kate Winslet lost supporting actress honors to Alicia Vikander for The Danish Girl. Fourteen of the last 21 supporting actress winners went on to claim the Oscar.
