Rocket Monkeys Voices and Behind the Scenes
Rocket Monkeys blends space hijinks with bright animation and snappy humor, entertaining audiences across Canada and the United States. The show follows two mischievous brothers, Gus and Wally, as they tackle outlandish missions that rarely go as planned. The star voices come from Seán Cullen as Gus, Mark McKinney as Lord Peel, and Mark Edwards as Wally. When the series premiered on Teletoon, it quickly built a following thanks to its bold energy, quick banter, and vivid character dynamics. This piece draws on conversations with the cast to reveal how the characters came to life, how recording works, and why audiences keep tuning in.
What was the inspiration for each of your characters?
Seán Cullen describes Gus as carrying a heavy, self important tone that lands with comic effect, a voice he compares to the gravitas of Charlton Heston. The choice gives Gus a weighty presence that contrasts with the chaos around him. Mark Edwards explains that Gus tries to project seriousness while Wally leans into pure silliness, a dynamic reminiscent of classic duos from the era of cartoons like Pinky and the Brain, Ren and Stimpy, and SpongeBob and Patrick. Mark McKinney portrays Lord Peel as a frustrated everyman who snap tests under pressure; a character who initially seems human yet ends up appearing banana shaped, a playful coincidence that fuels his villainous turn when he encounters the Rocket Monkeys. These contrasts create a trio with distinct voices and comic chemistry. (Interviews with the cast)
Do you record your parts together or separately?
Mark Edwards notes that he and Seán Cullen often record scenes side by side, which can enhance their on mic chemistry. Mark McKinney would love to join them in the booth whenever possible because it makes the experience feel like a team workout. Seán Cullen explains that while many sessions are done separately, there is something special about catching an organic moment when actors perform with one another. Those rare collaborations help capture the spontaneity that fans hear in the final mix. (Interviews with the cast)
What other misconceptions are there about the voice recording process?
Mark McKinney jokes about free water and the old rumor that voice actors record naked, which is obviously not the case. Mark Edwards mentions a common misconception that animation is completed first, a belief that stems from familiar scenes in classic films like Mrs. Doubtfire. Seán Cullen points out that in earlier days, voice work sometimes happened after animation, which could be brutal because timing had to be perfect after the visuals were set. The reality today is a blend of preparation and improvisation, with actors discovering lines in the moment rather than simply reciting them. The work is demanding and far from glamorous, but it remains deeply rewarding for performers who thrive on character and collaboration. (Interviews with the cast)
How do you get work done when you’re constantly joking with each other?
Mark McKinney explains that a practical approach helps. A no joking banner goes up to keep sessions focused, shaving hours off the day. Mark Edwards adds that the fun continues between takes, with Sean and he often singing, rapping, ribbing, or even pretending to be other people. Seán Cullen emphasizes that the joy of working with others makes the job special, and that collaboration is a big part of what keeps performances fresh and energized. The blend of discipline and play drives a strong, authentic energy that audiences pick up in the show. (Interviews with the cast)
