Written and executive produced by Higginbotham and Pollack, Happy Accident revolves around two Pittsburgh families — a father, Bud (Walsh), with three adult daughters (Swisher as Eleanor), and a hotel lounge singer (Williams as Sherri) with her med student son (Knight)— who are forced together after a decades-old secret is revealed.

Pinnick will play Samantha “Sammy” Bennett, the baby of the family and a tomboy. Knight is Kenan, Sherri’s son, who has a need for control and order.

Pinnick is known for playing the titular role in feature Princess Cyd. She’s repped by Brillstein Entertainment Partners and Innovative Artists.
