The actor, just 20 years old, died July 6 from a seizure caused by epilepsy. One of his last projects he filmed before his sudden death was Descendants 3, which premiered Friday on Disney Channel. Out of respect for his family and loved ones, the network canceled the Descendants 3 red carpet premiere and instead, The Walt Disney Company made a donation to the Thirst Project, a philanthropic organization to which Cameron was deeply committed. Plus, with permission from the Boyce family, the telecast of Descendants 3 was dedicated in his memory.
