Alex Borstein, Alison Brie, Rachel Brosnahan, Jane Fonda, and Lily Tomlin were all nominated for the award on Sunday
And the winner is… Rachel Brosnahan!
In her speech, Brosnahan expressed her disbelief to be accepting the prestigious award and went on to honor the people who helped bring the Amazon show to life.
“I’ve wanted to be an actor for as long as I can remember, and to be able to count all of you in the room as my peers, and let alone stand on this stage is beyond my wildest dreams,” the actress began.
After thanking her publicists, lawyers, and Maisel co-stars, Brosnahan made sure to mention two important people on set, who don’t get as much praise as she felt they deserved.
“Our two often unsung background actors who work the same hours as us and share the same union as us,” she said. “I couldn’t be luckier to be a part of this amazing group of artists.”

This is Brosnahan’s second SAG nomination. In 2015, she was nominated with the cast of House of Cards for best ensemble in a drama series.
Maisel won the big three SAG awards in the comedy series categories, including outstanding performance by a male actor for Tony Shalhoub and the nine-member cast won for best ensemble. 30 Rock was the only show since 2008 to sweep all three comedy categories.
Brosnahan, 28, is coming off a hot awards season, in which she already nabbed best performance by an actress in a television series, comedy or musical at the Golden Globes and outstanding lead actress in a comedy series at the 2018 Emmys.

The actress plays Miriam “Midge” Maisel, a New York City housewife, who launches her career in stand-up comedy after discovering her husband cheated on her, on the hit Amazon show.
Of the series’ critical acclaim, Brosnahan previously said, “We’re so happy that we have found an audience and our audience has stayed with us through season two and hopefully more to come.”
Season 1 of Maisel recently debuted its second season in December. Before season 2 even premiered, the series was renewed for a third run.
The 25th annual Screen Actors Guild Awards, hosted by Megan Mullally, were broadcast live from Los Angeles on both TNT and TBS.
