Exclusive: Happy Face has rounded out its series regular cast, adding Khiyla Aynne (Circuit Breakers) and Benjamin Mackey (The Morning Show) alongside Annaleigh Ashford, Dennis Quaid, James Wolk and Tamera Tomakili. David Harewood (Homeland) also joins the upcoming Paramount+ drama series in a recurring role.

Happy Face is inspired by the true-life story of Melissa Moore; the Happy Face podcast from iHeartPodcasts and Moore; and the autobiography Shattered Silence, written by Moore with M. Bridget Cook.

In the series, jumping off from Moore’s true-life story, Happy Face (Quaid) is an incarcerated serial killer who also is Melissa’s (Ashford) once-beloved father. After decades of no contact, he finally finds a way to force himself back into his daughter’s life.
