William Desrosiers and the Voice of Rocky in PAW Patrol: The Dino Movie

At just twelve years old, William Desrosiers has already landed one of the most coveted voice roles in Canadian children’s animation. Born on September 19, 2013, in Cornwall, Ontario, the young actor steps into PAW Patrol: The Dino Movie (2026) as Rocky, the mixed-breed recycling pup taking over the character from Callum Shoniker, who had voiced Rocky across the franchise’s two previous theatrical films. The casting, announced by Spin Master Entertainment in May 2025 alongside a star-studded adult ensemble that includes Jameela Jamil, Terry Crews, Snoop Dogg, and Jennifer Hudson, placed Desrosiers among a new generation of child performers breathing fresh energy into the beloved pups.

Rocky and the PAW Patrol Film Franchise

Rocky has rotated through a long line of voice actors across the PAW Patrol television series and its theatrical run. For The Dino Movie, directed once again by Cal Brunker, the role passed to Desrosiers as part of a broader recast of the core pup lineup. The film picks up after PAW Patrol: The Mighty Movie (2023) and sees the pups crash-land on an uncharted island teeming with dinosaurs, with the team forced to contend with their recurring rival Mayor Humdinger. Rocky’s character a resourceful, mechanically-gifted pup with a recycling mission demands a voice that carries both ingenuity and warmth, qualities Desrosiers brings to a franchise that has generated over $350 million globally across its first two films. The Dino Movie is set for theatrical release on August 14, 2026.
