The cast of the popular 2000s drama "Heroes" has faced a series of personal and professional difficulties since the show concluded its four-season run in 2010. The series, which debuted in 2006 and centered on ordinary people discovering superhuman abilities, garnered critical acclaim and numerous awards, including a Television Critics Association Award for Program of the Year. However, for many of its breakout stars, the aftermath of the show's success has been marked by health battles, workplace allegations, financial issues, and legal entanglements.
Hayden Panettiere's Struggles and Passing
Hayden Panettiere, who played Claire Bennet and became a breakout star at 17, publicly struggled with addiction and postpartum depression after the birth of her daughter in 2014. She recounted the challenges of postpartum depression, stating that it's a spectrum many women experience and that it needs to be openly discussed. Following the filming of her series "Nashville," Panettiere took a break from acting. In 2018, she relinquished full custody of her daughter to ex-partner Wladimir Klitschko, citing severe postpartum depression, anxiety, and addiction to alcohol and opioids. She was hospitalized for jaundice, with doctors warning of liver failure, and subsequently spent eight months in rehab.
Panettiere's relationship with Brian Hickerson was also marked by legal issues. Hickerson was arrested for domestic violence in May 2019, and later faced eight counts of domestic violence and assault in February 2020. Panettiere issued a statement at the time, expressing hope that her experience could serve as an example for others. The couple reportedly split, with Hickerson stating they were "just friends."
Tragically, Panettiere's brother, Jansen, died unexpectedly in 2023 at the age of 28. Panettiere described his loss as losing "half my soul." In May of the same year, shortly before her death, Panettiere expressed optimism about her future in an interview promoting her memoir, "This Is Me: A Reckoning," stating she felt she had "shaken off all of this darkness and this negativity."
On August 16, Panettiere was found unresponsive in an apartment in Greenville, South Carolina, and was pronounced dead at the scene. The cause of death is under investigation pending toxicology results, but a suspected overdose was mentioned.
Other Cast Members' Challenges
Milo Ventimiglia, who played Peter Petrelli, experienced a year-long dry spell in his career after "Heroes" concluded, during which he considered leaving Hollywood. His career later rebounded significantly with the series "This Is Us." In 2025, Ventimiglia and his wife, Jarah Mariano, lost their Malibu home to wildfires.
Ali Larter, who portrayed multiple characters, went on to have a successful career in other projects. However, she became involved in a controversy surrounding actor Leonard Roberts's departure from "Heroes." Roberts published an open letter alleging backstage friction and systemic racism, naming Larter as a factor in his early exit. He described tension on set regarding intimate scenes, and claimed his character's departure was linked to "the Ali Larter situation." Show creator Tim Kring acknowledged a lack of diversity among the show's senior staff. Larter expressed sadness over Roberts's allegations, stating his perception did not match her memory of their relationship, but apologized for any role she may have played in his negative experience.
Adrian Pasdar, who played Nathan Petrelli, underwent a highly publicized and contentious divorce from Dixie Chicks singer Natalie Maines that lasted years and impacted his finances. They eventually reached a private financial settlement in December 2019 after a bitter legal battle.
Greg Grunberg, who played Matt Parkman, has faced personal health challenges. His oldest son, Jake, was diagnosed with severe epilepsy at age seven. Grunberg has been an advocate for epilepsy awareness. The actor also developed alopecia, which he believes was triggered by knee replacement surgery, and has been diagnosed with Hashimoto's disease, a thyroid condition.
