LOS ANGELES (AP) Tiffany Haddish led an African-American sweep of Emmy Awards for TV series guest actors, a landmark moment in the entertainment industrys effort to foster diversity.

Haddish was honored at Saturdays creative arts Emmys for hosting Saturday Night Live , while Katt Williams won the guest comedy actor award for Atlanta.

Ron Cephas Jones of This Is Us and Samira Wiley of The Handmaids Tale accepted guest acting honors in the drama series categories.

Cephas, who plays a father who reconnects with his son (series star Sterling K. Brown) after a difficult life of drug addiction and loss, was asked backstage if his character would have been on TV in the past.

No. Not in this incarnation. ... Not that the audience wasnt ready for it. But maybe the executives, or people that have a say in the writing, probably wouldnt have been ready for this kind of thing. But now we are. Were moving forward and moving ahead.

In another step forward Saturday, Shauna Duggins became the first woman to win an Emmy for stunt coordination for a comedy or variety series for GLOW, about womens wrestling in the 1980s.

The creative arts Emmys set the table for NBCs Sept. 17 main ceremony, which could also advance inclusivity on-screen and off. Donald Glover, the star and creator of Atlanta, won trophies last year for acting and directing and is a multiple nominee again, with his show a top contender for best comedy.

Tracee Ellis Ross of black-ish and Issa Rae of Insecure are competing for comedy series acting honors. On the drama side, Brown could repeat as best actor for This Is Us, with Jeffrey Wright of Westworld among his competitors, while Killing Eve star Sandra Oh could become the first actress of Asian descent to win the top award.

Haddish, a hot property since her breakout performance in the movie Girls Trip, has been an Oscar presenter and MTV Movie & TV Awards host. She co-stars in the sitcom The Last O.G.

She was a no-show at the Emmys, but presenter Tichina Arnold had fun accepting for her.

Tiffany couldnt be here tonight. But, guess what, Tiffany! Ive got your award, girl! Arnold said, holding up the statuette triumphantly.

I think youre going to have to give that back, presenter Gerald McRaney (This Is Us) teased her.

The Star Trek television franchise received the Governors Award. William Shatner, star of the original 1960s series, and Sonequa Martin-Green of 2018s Star Trek: Discovery accepted the award, along with other actors with Star Trek credentials including Walter Koenig, Jeri Ryan and Levar Burton.

Star Trek has endured because it represents an ideal that is greater than the sum of our parts, Shatner said. The hope of Star Trek is not just that it shows us what we can be tomorrow. But the real hope is how its been embraced and watched and reached to see the best version of ourselves.

An edited version of the two-part creative arts ceremony, held Saturday and Sunday, will be telecast on FXX at 8 p.m. EDT Saturday, Sept. 15.
