Spoiler warning: This piece discusses plot points from the March 16 episode of Memory of a Killer.

From McDreamy to a very different man

Patrick Dempsey, who spent 11 seasons as Dr. Derek Shepherd on Grey’s Anatomy, now stars as Angelo on Fox’s Memory of a Killer. Angelo is a contract killer struggling with early-onset Alzheimer’s while trying to keep his violent work separate from his home life. The role is a big departure from the romantic lead people still associate with Dempsey.

Why he said yes

Dempsey says the mix of the assassin angle and the depiction of dementia drew him in. He was surprised by how quickly the offer came and had to decide within about 24 hours. He told reporters that roles like this do not come his way very often, and the material felt both challenging and urgent.

What the show is doing

Inspired by a book and the 2003 Belgian film De zaak Alzheimer, Memory of a Killer turns Dempsey’s good-guy reputation into a tool for making Angelo an unexpectedly sympathetic antihero. The series juggles three main threads: family drama, procedural investigation, and action. That mix is deliberate and aimed at keeping the story both emotional and entertaining.

  • Angelo’s daughter, Maria, played by Odeya Rush, is pregnant and becomes a target tied to Angelo’s other life.
  • Angelo’s brother Michael, portrayed by Richard Clarkin, is living in a memory care facility, which forces Angelo to confront the caregiver role.
  • Angelo’s boss is Dutch, played by Michael Imperioli.

How the show reveals Angelo

The season operates on a roughly three-month timeline, while episode five flashes back five years to fill in Angelo’s backstory. Dempsey says those early episodes were a balancing act: should the audience meet Angelo as the suburban father first or as the assassin? The series chose to do both, and episode five is where many pieces click into place.

Portraying Alzheimer’s without over-explaining

Dempsey has been involved in health causes for years and saw this series as a chance to bring more attention to Alzheimer’s and the strain it places on families and caregivers. He and the creative team pushed to keep some moments private and internal, rather than spelling everything out. Small errors and hallucinations are used to show Angelo’s decline: forgetting a security code, putting a gun in the wrong place, losing his way in the woods, and seeing his brother in visions.

Those private moments are meant to force viewers to pay attention and to feel the character’s confusion and fear, rather than rely solely on plot exposition.

How long could a show like this last?

As executive producer, Dempsey acknowledges that Alzheimer’s can progress quickly, but he also points out that scientific breakthroughs and care options are evolving. If the series is renewed, he would like to explore what can be done to slow progression and to show the emotional and financial toll on families. He emphasizes that the caregiver story is central and under-discussed.

Action, stunts, and staying fit

Dempsey, an experienced racecar driver, performs his own driving and enjoys the physical work. Playing an action-oriented character has motivated him to maintain strict fitness and health habits as he heads into his 60s.

Living with the McDreamy legacy

Dempsey accepts that Derek Shepherd will always be part of his public image, and he uses that visibility to advance causes he cares about, including the Dempsey Center and colorectal cancer awareness. He says the show gave him a platform to reach people and to encourage more holistic care for patients and families.

Personal notes: family and loss

His children mostly do not watch his work, though his daughter has watched this new series. He also reflected on the recent death of Eric Dane, a former Grey’s Anatomy co-star who passed away after battling ALS. Dempsey said losses like this sharpen your sense of what matters and reinforce the importance of using your platform for positive work.

Production life

Memory of a Killer filmed in Toronto, where cast and crew endured cold winter conditions and long hours. Dempsey praised the local crews and expressed hope the show will return to the city for another season.

Where to watch: Memory of a Killer airs Mondays at 9/8c on Fox, with episodes available the next day on Hulu. The season finale was scheduled for April 9.
