Patrick Dempsey is making his broadcast television comeback. The former Grey’s Anatomy star will lead Fox‘s new psychological thriller Memory of a Killer. The series premieres this January 2026. Dempsey plays Angelo Ledda, a hitman battling early-onset Alzheimer’s while leading a double life.

🔥 Quick Facts:

  • Patrick Dempsey returns to network TV after years away from broadcast.
  • Series premieres on Fox in January 2026 as a midseason entry.
  • Dempsey plays an NYC hitman who is also a Cooperstown photocopier salesman.
  • Early-onset Alzheimer’s threatens his carefully compartmentalized two lives.

What Happened: Fox Drops Official Teaser for New Thriller

Fox released the first teaser for Memory of a Killer on October 24, 2025. The promo shows Dempsey‘s complex character living two separate identities. He’s a fearsome NYC contract killer by trade. Upstate, he’s a mild-mannered photocopier salesman and devoted father. The teaser hints at his devastating diagnosis.

The show draws inspiration from the 2003 Belgian film The Memory of a Killer. That movie also centered on an aging hitman facing Alzheimer’s. Fox Entertainment and Warner Bros. Television produced the series. Ed Whitmore created and wrote the adaptation.

“Angelo Ledda has built and maintained a brick wall between his two worlds for years. But early-onset Alzheimer’s is a foe he can’t outrun.”

Why This Matters: Dempsey’s Major TV Return

Patrick Dempsey is a household name to millions. He spent 11 seasons on Grey’s Anatomy as Dr. Derek Shepherd. His departure from the show shocked fans. Now, he’s ready for broadcast television again, and it’s a bold choice. Memory of a Killer shows a darker side of his acting abilities.

This role requires Dempsey to shed his romantic leading-man image. He becomes a hardened criminal battling cognitive decline. The two-life narrative offers rich dramatic potential. Viewers get a hitman thriller mixed with personal family drama. Network television rarely takes such compelling risks.

The timing matters too. Fox needs strong dramas for 2026. Dempsey’s star power brings instant credibility. His fanbase remains devoted after decades in the spotlight. The January premiere spots the show in a competitive midseason slot.

The Details: Cast, Network, and Production Team

Here’s everything you need to know about Memory of a Killer:

Title Memory of a Killer
Network Fox
Premiere Date January 2026 (Midseason)
Lead Actor Patrick Dempsey as Angelo Ledda
Supporting Cast Michael Imperioli, Richard Harmon, Odeya Rush, Gina Torres
Production Company Fox Entertainment, Warner Bros. Television
Creator Ed Whitmore
Plot Hitman with two lives faces early-onset Alzheimer’s while juggling identities

The cast lineup is particularly strong. Michael Imperioli (known for The Sopranos) plays a key supporting role. Richard Harmon brings intensity to the ensemble. Odeya Rush and Gina Torres round out the compelling cast. This ensemble has serious credential behind it.

Fox green-lit the series as a straight-to-series order. That means Dempsey and the creative team got immediate confidence from executives. The 2025-2026 season order came directly without a pilot phase.

What To Watch For: Season One Developments

  • How the Alzheimer’s storyline affects Angelo’s professional hits.
  • When his family discovers his true career assassination business.
  • The relationship dynamics between his two separate worlds colliding.
  • Whether Angelo’s past victims or rivals exploit his cognitive decline.
  • How the supporting cast reacts to his devastating diagnosis.

Season one likely explores the tension between two identities. Angelo has maintained this split for years. Alzheimer’s threatens everything he’s built. Memory loss creates a ticking clock for violence. Will he remember his targets? Will he forget his family? These questions drive the narrative.

The show could run multiple seasons if viewers connect with the premise. January premieres often build momentum through winter sweeps. Strong critical reception could secure Dempsey’s future at Fox.

Is This Dempsey’s Most Dramatic Role Yet?

Patrick Dempsey has built a successful career across decades. Grey’s Anatomy made him a worldwide heartthrob. He’s done films, directed, and pursued professional racing. But Memory of a Killer might be his darkest character study. Playing a hitman with Alzheimer’s requires emotional range.

The role strips away romantic leading-man appeal. Dempsey must portray vulnerability and danger simultaneously. His character faces mortality in multiple ways: violent enemies and memory loss. That psychological complexity separates this role from his prior television work. Can Dempsey deliver a career-defining dramatic performance?
