In 1987, the world fell for a pair of Tucson teenagers. One was a nerd with a lawnmower, the other was the quintessential "it" girl in a white suede jacket. Patrick Dempsey and Amanda Peterson didn't just star in a movie; they defined an era of high school longing.
When you watch Can't Buy Me Love now, it hits different. There is a raw, electric chemistry between Dempsey’s Ronald Miller and Peterson’s Cindy Mancini that feels too real for a standard 80s rom-com. It’s the kind of magic that makes you wonder what happened after the cameras stopped rolling.
The truth is, their lives went in polar opposite directions. While Patrick Dempsey eventually became "McDreamy" and a global superstar, Amanda Peterson walked away from Hollywood entirely. Her story ended in a way that remains one of the industry's most quiet, lingering tragedies.
The Chemistry That Made "Can't Buy Me Love"
People forget that the movie was originally titled Boy Rents Girl. It sounds a bit cynical, right? But once the producers secured the rights to the Beatles' song, the vibe shifted. It became something softer, more meaningful.
Dempsey was only 21 during filming, and Peterson was even younger—just 15. Think about that. At 15, she was carrying the weight of a major studio film. She had this incredible ability to look like the most popular girl in school while simultaneously showing you how lonely it felt to be her.

On set, they were professional and convincing. Dempsey has often looked back at that time as a pivotal moment for his career. He was just a kid from Maine with a shock of dark hair and a lot of energy. Peterson, meanwhile, was already a veteran of the screen, having appeared in Annie and Explorers.
Why Amanda Peterson Left Hollywood
By 1994, Amanda was done. She was only 23. It’s rare to see someone at the height of their "teen idol" status just pack up and go, but that’s exactly what she did. She moved back to Greeley, Colorado.
Honestly, the "why" behind her exit is heartbreaking. In a 2015 interview on The Doctors, her family revealed a trauma she had kept secret for decades. While she was a rising star at age 15, she was sexually assaulted. She didn't tell anyone at the time. She just kept working, kept smiling for the cameras, and kept playing the "perfect" girl.
That kind of trauma doesn't just go away. It manifests. For Amanda, it led to a lifelong struggle with her mental health and substance use. She tried to find a new path, enrolling in college and starting a family, but the shadows from her Hollywood days followed her to Colorado.

The Tragic News That Shook Patrick Dempsey
Fast forward to July 2015. The news broke that Amanda Peterson had been found dead in her Greeley apartment. She was only 43.
The autopsy later confirmed it was an accidental overdose. She had been dealing with several health issues—sleep apnea, pneumonia, and recovery from a recent hysterectomy. She had a mix of medications in her system, including morphine she’d gotten from a friend to help with the pain. Her body simply couldn't handle the "morphine effect," and she died from respiratory failure.
Patrick Dempsey, who hadn't seen her in years, was clearly shaken. He took to Twitter (now X) to share a short but deeply felt tribute. He said, "In my memory, she will always be vibrant and young. Gone too soon."
It was a sentiment shared by an entire generation of fans. To us, she was frozen in time, sitting on top of an airplane in that Tucson graveyard, teaching us all about "the African Anteater Ritual." Seeing that image clash with the reality of her final years was a gut punch.

What Most People Get Wrong About Their Relationship
There’s a common misconception that Dempsey and Peterson were a "thing" in real life or stayed best friends for decades. That wasn't the case. Hollywood is a workplace. They were co-workers who shared a monumental experience, but as Dempsey’s career took off into the stratosphere of Grey’s Anatomy, Amanda’s life became very private and, at times, very difficult.
Between 2000 and 2012, Amanda was arrested several times for various offenses, including DUI and possession. These "mugshot" stories often overshadowed the person she actually was. Her mother, Sylvia, always maintained that Amanda was a person of great humor and a lover of history. She wasn't just a headline; she was a daughter and a mother who was hurting.
The Legacy of Cindy Mancini
Why does this story still matter? It matters because it’s a reminder of the human cost of early fame. We see Patrick Dempsey and think of the "success story," but Amanda’s narrative is just as important. It highlights the need for better support systems for young actors and the long-term impact of untreated trauma.
If you’re a fan of 80s cinema, do yourself a favor and re-watch the film. Don't just look at the fashion or the goofy dancing. Look at Amanda Peterson’s eyes. She was a powerhouse of a performer who deserved a much longer, much happier second act.
Practical Steps for Fans and Film Historians
If you want to honor her memory or dive deeper into this era of film, here are a few things you can actually do:
- Watch her earlier work: Most people only know her as Cindy, but she was brilliant in the 1986 miniseries A Year in the Life. She won a Young Artist Award for it, and it shows her range way beyond the "cheerleader" trope.
- Support Trauma Resources: Since her family went public with her history of assault, many fans have donated to organizations like RAINN (Rape, Abuse & Incest National Network) in her name. It’s a way to turn a tragedy into something that helps others.
- Keep the memory accurate: When discussing her, move past the "downward spiral" narrative. Acknowledge the accidental nature of her passing and the health struggles she was navigating at the end. She was trying to heal, not trying to leave.
- Appreciate the Craft: Notice the choreography in Can't Buy Me Love. It was actually done by a young Paula Abdul. It’s one of those "small world" Hollywood facts that makes the movie even more special.
The story of Patrick Dempsey and Amanda Peterson is a tale of two different paths, but for 94 minutes in 1987, they were the center of the universe. That’s how most of us choose to remember them.
