Dennis Quaid Dives Deep into the Chilling Psychology Behind Happy Face: “It’s Really About Ourselves”
Dennis Quaid is no stranger to complex roles, but his latest turn in Happy Face may be one of his most disturbing—and profound—performances yet, based on Keith Jesperson. The Paramount+ psychological drama, which airs its season finale on May 1st, features Quaid as a chilling figure in a series based on the true story of a serial killer and the daughter who ultimately turned him in. Speaking to JustWatch in a recent interview, Dennis Quaid reflected on the show’s unsettling emotional depth.
“What I found fascinating about Happy Face is that it wasn’t your typical story of a serial killer,” he said. “It was really this relationship between the father and the daughter.”
That complex relationship sits at the core of the show’s psychological tension. Happy Face is adapted from the real-life story of Melissa Moore, who discovered in her teenage years that her father, Keith Jesperson, was the notorious “Happy Face” serial killer. The show weaves through their shared past, the trauma of revelation, and the uneasy love that persists even in the face of an unspeakable truth.
For Dennis Quaid, known for charismatic roles in films like The Parent Trap and more recently The Substance, Happy Face marks a dramatic shift. His portrayal of Keith Jesperson is grounded in realism rather than sensationalism. Instead of leaning on cliché depictions of psychopathy, he explores the emotional and psychological aftermath such a revelation has on a family.
“Serial killers in a way are very easy to play because they don’t really have any empathy and feelings,” Dennis Quaid explained. “We all have that capability maybe inside of us, or we suspect we do, so it gets down to human nature—and the question becomes really about ourselves.”
That last line—“It’s really about ourselves”—summarises why Happy Face is more than just a dark thriller. It forces audiences to question the nature of evil, empathy, and identity. Could someone you love be capable of something horrifying? And what does that say about you?

The psychological drama has resonated with viewers. According to JustWatch, Happy Face climbed 11 spots in their U.S. streaming charts this week, landing at #36, and it may go higher after the finale airs. Quaid’s quote now features on the show’s Why to Watch page on the platform, adding even more visibility to the series.
