In the This Is Us episode “Still There,” while Randall (Sterling K. Brown) and Beth and their daughters adjust to having another daughter in the family, Kevin (Justin Hartley) deals with a setback on his movie. And in the past, Jack (Milo Ventimiglia) and Rebecca (Mandy Moore) are visited by an unwelcome guest, Rebecca’s mother Janet.
Janet is portrayed by Elizabeth Perkins. She’s known for her roles on How to Live with Your Parents (Elaine Green), Weeds (Celia Hodes), and in the films Ghostbusters (Phyllis Adler), Must Love Dogs (Carol), Big (Tom Hanks’ girlfriend) – see link above, The Flintstones (Wilma), and About Last Night…(Joan), among others. This Is Us airs Tuesdays at 9pm on NBC, right after The Voice.
