Peter Serafinowicz’s well-fed comedy creation Brian Butterfield is to make his first appearance for CBBC later this year in a new series for children called Fit.

The show, which is being developed by Horrible Histories makers Citrus Television, is a sketch series themed around sport and exercise which is currently being road-tested with audiences of youngsters before the show debuts in the autumn.

Inspired by actor Brian Soper’s infamous Personal Injury Helpline TV commercials, Butterfield was first seen in the 2009 series of The Peter Serafinowicz Show and has since taken on a Keith Lemon-style life of his own, appearing as a panellist on Shooting Stars and cropping up in Serafinowicz’s BBC Radio 6 music show.

While Butterfield is the only character Serafinowicz will play in Fit, he’ll be joined in the series by Canadian comic Tony Law.

Butterfield's upper-crust accent, trim moustache and roly-poly figure will no doubt make the character a favourite figure of fun for CBBC viewers. See him in action presenting an ad for The Butterfield Diet below:
