you’d never know it wasn’t Peter Sallis in Vengeance Most Fowl thanks to expert vocal mimicry

The release of a new Wallace and Gromit film has always been much anticipated in our house, and this year was no different. Like many others, we snuggled under the blankets after a full Christmas day (in every sense), ready for the release of Vengeance Most Fowl (2024). Four years in the making, it was produced by Aardman Animations and the BBC, in association with Netflix, and was Wallace and Gromit’s sixth film, and second feature-length film after The Curse of the Were-Rabbit (2005).
We were halfway through this claymation, stop-motion spectacle before I remembered that Wallace’s voice was not being played by actor Peter Sallis, who sadly died in 2017, but instead had been seamlessly voiced by someone else. A quick Google search later to see if an AI voice had been used in the production (as is a developing trend), I was delighted to find that British actor, Ben Whitehead, had voiced the part.
Eager to know more about how he prepared, I discovered that as a fan of the first film, A Grand Day Out (1989), he grew up doing voices, accents and impressions as a boy. In 2003, a friend at Aardman hired him as a voice actor for Were-Rabbit. By 2005, he was Sallis’s understudy and by 2009, he was Wallace’s voice full-time, owing to Sallis’ failing health.
Vocal mimicry isn’t limited to animation alone. Many biographical musicals, such as Tina: The Tina Turner Musical, rely on excellent celebrity impressions to wow the crowds. Biographical films such as Lincoln (2012) have actors such as Daniel Day-Lewis impersonate the historical figure of Abraham Lincoln, while Bradley Cooper, in the film A Star is Born (2018), trained his voice for over a year for the role, to sound just like country rock star, Jackson Maine.
Actors such as Luke Kempner, have branched into comedy as impressionists, voicing celebrities in sketches such as Spitting Image (2020-21). Many bands and singers spend entire careers working as tribute bands or celebrity impersonators of stars, such as Elvis.
In this growing CGI and AI-voice world, there was something refreshing about being entertained as a family with more “traditional”, human methods of animation and voice-acting craft. Hat’s off to Whitehead for his Wallace and I think that many an actor and performer could learn a thing or two from Whitehead’s craft of vocal mimicry.
