Jonathan Brandis died by suicide on November 12, 2003, at the age of 27. He was found hanging in the hallway of his Los Angeles apartment and was transported to Cedars-Sinai Medical Center, where he died from the injuries sustained. Brandis had been struggling with depression and career difficulties, including a lull in his acting career and disappointment over his reduced role in the film "Hart's War." His father later mentioned that Jonathan likely suffered from bipolar disorder, which contributed to his mental health struggles leading to his death.
