Entertainment TV Disney's 'Descendants 3' : When Does It Premiere, and How Will It Honor Cameron Boyce? Cameron Boyce, who has played Cruella De Vil's son Carlos since the first Descendants four years ago, died July 6 at age 20 By Tom Gliatto Published on August 2, 2019 02:47 PM Share Tweet Pin Email With its nicely rounded story and message of inclusion, Descendants 3 is possibly the best in this popular series of family-oriented Disney movies. It’s the saddest too: Cameron Boyce, who has played Cruella De Vil’s son Carlos since the first Descendants four years ago, died July 6 at age 20. He has several sweet moments that stand out in this busy, bustling ensemble entertainment. In one he makes a sentimental little birthday present for Jane, the Fairy Godmother’s daughter (he tells her he used a 3D printer), and he also gets a last spirited bit of dialogue at the very end.

Dove Cameron Recalls the Devastating Moment She Learned About Cameron Boyce’s Death Feeling upstaged, Audrey decides there’s no benefit to being a Disney princess, singing, “I never thought of myself as mean/ I always thought that I’d be the queen/ And there’s no in-between.” Soon she’s cackling madly and mucking around with spells. The telecast will also be dedicated in Boyce’s honor. Descendants 3 premieres Friday at 8 p.m. ET on the Disney Channel.
