Academy Award winner Louise Fletcher, infamous for her Oscar turn as sadistic Nurse Ratched in One Flew Over the Cuckoo’s Nest, made a perfect casting as Winn Adami, the "bad girl" holy vedek who stuns everyone by later winning election as kai. 

Fletcher, a 1934 native of Birmingham, Ala., was first seen in the Season 1 finale, “In the Hands of the Prophets,” and turned up in 14 episodes right through the series finale, “What You Leave Behind.” 

Among her long career, Fletcher also won a genre Saturn Award for her role in Brainstorm, and had a Saturn nomination for the horror film Flowers in the Attic.  Her two-part episode of CBS’ Picket Fences also earned her an Emmy nomination in 1996.  Other TV roles in her later career have come from The Practice, Wonderfalls, 7th Heaven, and three times on ER; her films credits also lean to the malevolent with titles like Firestarter, Mulholland Falls, Love Kills, Cruel Intentions, and Very Mean Men.
