While drew plenty of inspiration from real-life celebrities of the 1960s over the course of its five-season run, none were more central to the journey of Rachel Brosnahan's titular comedienne than Lenny Bruce, played by Luke Kirby.While only appearing in a few episodes per season, Kirby's Lenny had a profound impact on Midge as she traversed the grueling world of stand-up comedy. Whether they were sharing the backseat of a police car after being arrested or sharing the stage at The Gaslight, Lenny was a touchstone to the industry for Midge and a constant cheerleader if ever she started to doubt her talents.With 's series finale debuting on Friday — and the use of flash-forwards employed throughout the final season — many wondered how, or even if, the show would address the real-life fate of Bruce, who died of a drug overdose in 1966.The finale kicks off with Lenny onstage in 1965 San Francisco, a recreation of one of the final shows of the real-life comic's career.
