Gillian Anderson may be best known for her strong roles in The X-Files and The Fall, but she’s also an accomplished stage actress, and on Sunday evening she took home an award from the prestigious London’s Evening Standard Theater Awards for her work in A Streetcar Named Desire.

Anderson was among fellow theater actors Tom Hiddleston and Jeremy Herrin–who took Best Actor and Best Director, respectively–at the event, where she took home the trophy for Best Actress. According to The Daily Mail, Anderson was up against Helen McCrory for Medea, Kristin Scott Thomas for Electra, Billie Piper for Great Britain and Tanya Moodie for her performance in Intimate Apparel but beat them out with her stellar performance as Southern belle Blanche Dubois.

Anderson made headlines last month when she spoke out about the rampant sexism in Hollywood, calling it “intolerable”, around the same time The Fall writer Allan Cubitt was accused of threading misogynist overtones into the storyline of the show.

“It’s built into our society. It’s easy to miss and it’s easy to get used to it. There are things that are intolerable in today’s world, in terms of the perception of women. Whether they’re vamps or vixens… the expectation is that, if a woman is wearing a short skirt, she’s ‘asking for it,’” she said.
