“Mad Men” fans watched Kiernan Shipka grow up on the small screen in her role as Sally Draper, the daughter of Betty and Don. Her nuanced and captivating performance earned her critical acclaim and an older sophisticated fan base for such a young talent. Since then, Shipka, who was born in Chicago and raised in Los Angeles, has taken on a host of different projects, including Ryan Murphy’s “Feud” and the psychological horror film “The Blackcoat’s Daughter.” At the beginning of 2018, she stepped into the magical, mischievous world of half-human, half-witch Sabrina Spellman in Netflix’s “Chilling Adventures of Sabrina,” based on the Archie comic book series.

In this conversation, Shipka, who is about to turn 20, talks about her new film, “Let it Snow,” a teen drama about the friendships, love lives, and futures of a group of high school seniors, co-starring Shameik Moore and Isabel Moner. She also talks lessons learned growing up in the “Mad Men” world, what it’s like now to have a fan base closer to her own age, as well as her style philosophy, her go-to karaoke songs, and her love of a good power nap.
