In “Leanne,” Morgan’s titular character finds herself abruptly and shockingly single after her husband, Bill (Ryan Stiles), leaves her for another woman. Reentering the dating world after 33 years of marriage is confusing enough, but it also forces her to imagine the prospect of having to win over a new partner, with all that entails.

Leanne Morgan said she felt her career had peaked, but then she did something that turned everything around, and now she has her first-ever sitcom on Netflix.
