The How I Met Your Mother spinoff pilot has chosen its star– indie actress Greta Gerwig will play the lead role of Sally on How I Met Your Dad. Sally is “vibrant, messy and unpredictable” according to recently-leaked character breakdowns. She’s “a female Peter Pan who has never grown up and has no idea of where she’s going in life.” Gerwig will also serve as a producer and is expected to write. You might recognize Gerwig form her breakout role in Ben Stiller’s neurotic comedy Greenberg. Her recent lead in Frances, Ha earned her a Golden Globe nomination as well as much attention from the industry. Sally should be an easy character for her to play, since her role in the 2013 black-and-white comedy was also a mid-20s girl in New York who seemed to struggle with growing up and the responsibilities of being an adult.
