Yes, that storyline in Tig Notaro’s Amazon series was about Louis CK
When the second season of Tig Notaro’s Amazon series One Mississippi premiered this past September, much attention was drawn to a scene in its fifth episode, “Can’t Fight This Feeling”: A powerful man (played by Timm Sharp) masturbates in front of a woman (played by Stephanie Allynne) whose career he’s just given a leg-up. The character’s actions mirrored accusations of sexual misconduct on the part of One Mississippi executive producer Louis CK, accusations that have since been put on record by five women in a New York Times exposé. That same article confirms that the “Can’t Fight This Feeling” scene and the storyline that follows it are “a fictional treatment of the alleged masturbation episodes.”
