But this year there was a twist - only women spoke.
The annual show put the spotlight on women on Sunday, hiring its first-ever host, Frozen actress Kristen Bell, and handing all the award presenting duties to female stars.
The actress said being a part of "I, Tonya" made her sympathize with Harding in a way she hadn't before. SAG-AFTRA President Gabrielle Carteris said, "This is not a moment in time". Dreyfus, who had won the award five times earlier for Seinfeld and the rest for Veep, could not make it to the ceremony as she is undergoing treatment for breast cancer.
Actors Nicole Kidman and Alexander Skarsgard took trophies for playing unconventional spouses in "Big Little Lies", and "Veep" was voted the victor for Comedy Ensemble, with lead Julia Louis-Dreyfus also winning for the Selina Meyer role.
While the SAGs brought us more bold looks than the Globes, it wasn't without pared back looks proving simplicity is often the most striking approach. "I just beg that the industry stays behind us because our stories are finally being told". "I think my first initiative as First Lady will be cyberbullying...because I have yet to see any progress on that problem yet".
"I'm not the first female host".
Elisabeth Moss is here from the documentary The Handmaid's Tale. That's a sad one.
But Bell quickly got more serious. First LADY! I honestly never thought I would grow up to be the first lady, but you know what, I kind of like it.
The best: After taking the best drama Globe and cast SAG honor, Three Billboards Outside Ebbing, Missouri is as close as we have to a front-runner, so barring something freakish happening, that's definitely getting a nomination. The SAG red carpet saw the return of colorful frocks and far fewer Time's Up pins - although some actors, like Kumail Nanjiani and Gina Rodriguez, were still sporting theirs.
Brown had some advice for up-and-coming actors.
Asked how his standing in Hollywood has been changed by his recent success, he said: "You have your moment in the sun, there's no guarantee that you're going to keep working".
McDormand and Rockwell also both won Golden Globe awards in their respective categories, while the film won Best Drama Motion Picture. "I stand shoulder to shoulder with you and all the incredible women in this room who are trying to make things better".
Her co-star Alexander Skarsgard won the outstanding performance by a male actor prize for playing her abusive husband.
