Her 2018 play Superhoe was a collaboration between the Talawa Theatre Company and the Royal Court Theatre, directed by Jade Lewis. Lecky wrote and performed the monodrama,[1][12] and collaborated with British rapper The Last Skeptik on the play's music.[4][13]Superhoe follows the life of twenty-four year-old Sasha, and Lecky plays several characters.[14] She was inspired by a website that posted personal information on Instagram women involved in sex work.[6] Playwright Levi David Addai, who mentored Lecky around 2019, said in 2020 that she is "one of the most talented young writers, actresses, singer-songwriters in the country right now."[10]
Superhoe received positive reviews. The Evening Standard's reviewer said "[Lecky is] a revelation — singing and rapping eloquently as she delivers a knotty, occasionally grim story with charismatic fluency."[1]The Daily Telegraph's reviewer said "It stands squarely in the tradition of Royal Court writing while being its own fresh thing."[4]WhatsOnStage.com's reviewer said "She knows how to keep the audience on her side with just a backward glance, and her comic timing is superb."[14]The Guardian's reviewer said "Lecky engagingly performs her own writing ... Though rarely surprising, it's a simple story strongly told".[13]Stylist's reviewer said "...be sure to remember Nicôle Lecky. She’s a star slash genius."[15]The Times' reviewer said "The music is terrific, but, if anything, this show could easily use another song. The plot, however, never surprises us even for a moment. ... This is a shame because Sasha has got such sass and spark. You won’t find her at Wetherspoons; you really can’t help but like her."[16]
The BBC decided to adapt Superhoe as a TV-series, and the six part musical drama Mood premiered in 2022 on BBC Three. Lecky played the main character Sasha Clayton, was a series executive producer and writer, and was also involved in creating the music. The characters are those she performed in the play.[6][7][17] As part of her script-writing, she interviewed women involved in sex work online.[7][18] As of 2024, Mood has a 100% score on the review aggregator Rotten Tomatoes, based on five reviews.[19] Shortly after the premiere of Mood, Lecky was signed by the United Talent Agency (UTA).[20]
She has written a second drama for the BBC, which as of 2023 is untitled.[21][22] She plays Julia Blenkinsopp in the 2024 comedy drama Sweetpea.[23][24]
