Davis plays the role of Etta Candy in the 2017 filmWonder Woman. Her performance marked the first live action cinematic portrayal of that comic book character. Davis has said of the character: "She's a woman in a man's world and so being heard and seen aren't the easiest things, but it kind of doesn't deter her. Etta is unapologetically herself and I think that that's the thing that has drawn me to her the most... it took quite a while in my life to be unapologetically myself." Davis appears in the Netflix series The Chilling Adventures of Sabrina as Hilda Spellman.
