from Hayden Panettiere to Malcolm-Jamal Warner

Hayden Panettiere’s career began as an 11-month-old in commercials, before pivoting into roles in soap operas like Guiding Light and One Life to Live before she even turned nine. Her roles continued to expand, with some of her most memorable credits being the films A Bug’s Life (1998), Remember the Titans (2000), Ice Princess (2005), and Bring It On: All or Nothing (2006). Her leading turns in the shows Heroes and Nashville made her a household name.

Hayden struggled with addiction, mental health issues and postpartum depression after giving birth to her daughter Kaya in 2014. In August 2026, Hayden died at the age of 36 from an apparent cardiac arrest.

Hayden’s Ice Princess co-star Michelle Trachtenberg began her career primarily with Nickelodeon, thanks to the show The Adventures of Pete & Pete and the 1996 movie Harriet the Spy, all before she was even a pre-teen. Her most notable credits include the film EuroTrip (2004) and her regular stints in the shows Buffy the Vampire Slayer and Gossip Girl.

While reports and claims suggest Michelle struggled with addiction, she never addressed those herself. In February 2025, Michelle passed away at the age of 39 from complications of diabetes, seemingly stemming from a recent liver transplant.

Malcolm-Jamal Warner became one of the nation’s most popular young stars when he began appearing as Theodore Huxtable in The Cosby Show, a role he landed when he was 13 after making his TV debut just two years prior. The role earned him an Emmy nomination, and he parlayed that success into other TV credits like Malcolm & Eddie, Suits and The Resident.

In July 2025, Malcolm-Jamal accidentally drowned while in the ocean off the coast of Costa Rica at the age of 54, leaving behind his widow Tenisha Hancock and a daughter, who was eight years old at the time of his death.

After making his TV debut at the age of 12, River Phoenix became a star with his role in the 1986 film Stand By Me when he was 16. He cemented his spot as one of Hollywood’s brightest with acclaimed performances especially in 1988’s Running on Empty and 1990’s My Own Private Idaho, the former even earning him an Academy Award nomination.

In October 1993, River died at the age of 23 from an acute overdose of multiple drugs, including heroin and cocaine, although family and friends maintained he was never a regular user and dubbed his tragic loss as an accident. His siblings have entered show business as well, with his younger brother Joaquin Phoenix in particular now being an Oscar-winning actor.

Playing the adorable Arnold Jackson in Diff’rent Strokes made the young Gary Coleman one of the country’s most beloved stars, and he parlayed that into box office success in the ’80s and ’90s with films like On the Right Track (1981) and Jimmy the Kid (1982).

Throughout his life, however, Gary struggled with issues like bankruptcy and health problems, such as complications from heart surgery and depression. In May 2010, at the age of 42, Gary tragically passed away after an accident at his home resulted in an epidural hematoma.

Dana Plato was also part of the Diff’rent Strokes family, playing Kimberly Drummond, although was a recurring character in the show’s final two seasons when she became pregnant with her son Tyler. After the show ended, she pivoted to more adult-oriented work to distance herself from teen idol Kimberly.

Dana struggled with alcohol and drug abuse while making the show, and legal trouble followed her after the show as well. In May 1999, a day after appearing on The Howard Stern Show, the actress tragically died of an overdose of prescription drugs aged 34.

Cameron Boyce’s career on screen began in 2008 with the film Mirrors at just nine years old, but he rose to stardom with Disney, first in their TV series Jessie, and then when he was cast in their musical fantasy film franchise Descendants. He was also beloved in the industry for his focus on charitable work and philanthropy from a young age.

In May 2019, Cameron was found unresponsive at his home. He passed away at the age of 20 from an epileptic seizure caused by epilepsy, which his family revealed he had been suffering from.

Sawyer Sweeten was just a year old when he and his twin brother Sullivan (pictured above), plus their older sister Madylin, were cast in the sitcom Everybody Loves Raymond. The twins appeared on the show for nearly a decade, although after the show’s conclusion, Sawyer stepped away from the spotlight.

In April 2015, Sawyer tragically committed suicide at the age of 19. During the show’s 20th anniversary reunion special in November 2025, Madylin said of the work they’ve done since: “We’re very passionate in our family about suicide prevention. It is the second leading cause of death between ages 18 to 25. But 90 percent of people who seek treatment are cured.”

Heather O’Rourke became a horror icon with her film debut in the 1982 Oscar-nominated film Poltergeist, with her performance as Carol Anne Freeling still regarded as one of the genre’s greatest. She reprised her role in the film’s two sequels, and also appeared in shows like Happy Days and Webster.

In 1987, Heather was diagnosed with Crohn’s disease. In January 1988, she was rushed to the hospital for flu-like symptoms, but was diagnosed with intestinal stenosis and suffered cardiac arrest. Heather tragically passed the following day at the age of 12.

Daveigh Chase’s breakout role in the 2001 cult classic Donnie Darko, released when she was 11, paved the way for an illustrious career that included credits like the 2002 film The Ring, voice roles in Spirited Away (2001) and the titular Lilo Pelekai in Lilo & Stitch (2002), plus the TV show Big Love as a teenager.

After her final film roles in 2016, Daveigh became estranged from her family and struggled with substance abuse, experiencing financial difficulties and long periods of homelessness. She died in June 2026 at the age of 35 due to complications of AIDS.
