Indeed, Jim has hit prime-time TV playing a character that couldn't be further removed from the all singing, all dancing, all smiling sketches of Horrible Histories.
Instead, he's Aaron Mayfield, a convicted rapist who DI Alec Hardy (played by David Tennant) and DS Ellie Miller (Olivia Colman) are keeping a very close eye on as they continue to investigate the rape of Trish Winterman (Julie Hesmondhalgh).
Part five of the Series Three of the BAFTA-winning series - watched by over 10 million viewers - is on ITV at 9pm this evening.
"It's an honour and a thrill to play a part in such an outstanding show," said Jim, who agreed that his switch of roles had taken people somewhat by surprise.
