Co-star Chatwin says Panettiere was 'struggling' and 'really lonely' on her final film

Justin Chatwin, co-star of Hayden Panettiere's final film Sleepwalker, told People she appeared 'struggling' and 'really lonely' during the 2025 shoot and confided in him about trauma and addiction. Chatwin, sober 15 years, said he recognised the signs. Panettiere, who detailed those battles in her May memoir, died at 36. The Hollywood Reporter reported his account on 18 August 2026.
