Last week, Ryan Murphy gave Feud audiences a crash course on Joan Crawford (as played in the FX series by Jessica Lange)—showcasing her various eccentricities, vodka-fueled verve, and over-the-top glamour. But on this week’s episode, “The Other Woman,” Murphy turns toward Bette Davis (played by Susan Sarandon)—who, like Crawford, was a brash, studio-era rulebreaker, but with her own cocktail of peculiar characteristics. Ahead, a closer look at the traits teased in Sunday’s episode.

Her Number One Companion

Cigarettes were such a Davis signature that her Jezebel co-star Henry Fonda once joked, “I’ve been close to Bette Davis for 38 years—and I have the cigarette burns to prove it.”

They were not just accessories, either, but an extension of her already over-the-top self. Per biographer Ed Sikov, in his 2007 book Dark Victory: the Life of Bette Davis: “Cigarettes were to Bette Davis what a bottle of Southern Comfort was to Janis Joplin or a half-unbuttoned black shirt is to Tom Ford: a mundane prop elevated by sheer force of personality to the level of a stylized autograph.“ The book also quotes Dr. Ivin Prince: “She used smoking in a way I’d never seen before. It was a signature.“

She was so dependent on her signature Vanguards—of which she smoked up to four packs a day—that she could not abstain from them, even during a ten-minute television appearance. “If I did not smoke a cigarette,” she explained to TV talk show hosts, “they would not know who I was.” No one told Davis to put out her cigarettes, though, not even her dentist—who told Sikov that the actress smoked in both his waiting room and in the actual dentist’s chair. “She pretty much did what she wanted,” Prince said.

Davis’s accessory was so omnipresent and iconic that when the U.S. Post Office noticeably photoshopped out the actress’s cigarette, for a postage stamp in 2008, some Davis fans jokingly suggested a revolt.

She Had a Dirty Mouth and Wasn’t Afraid to Use It

In Sunday’s Feud episode, Davis storms into Crawford’s dressing room on a profanity-laced tear after she discovers that Crawford phoned in a gossip report about her. Although the New England-raised Davis was a self-described prude early in her life—remaining a virgin until she was married—she was fervently foul-mouthed (as this blooper reel attests). And her sharp remarks weren’t only ear-marked for annoying co-stars. (Though while we’re on the subject, one of her most well-known digs about Crawford was this: “She has slept with every male star at MGM except Lassie.”) Ed Sikov recounts, in Dark Victory, how she used profanity with loved ones as well—such as on the occasion of a surprise birthday party for her fourth husband Gary Merrill, during which she presented him “with an iced cardboard-prop cake that said, instead of ‘Happy Birthday,’ ‘Fuck You!’
