Smooth-voiced comedy wizard Peter Serafinowicz first cast a spell on us in the excellent and under-appreciated Tomorrow's World spoof Look Around You. But he's more than capable of carrying proceedings on his own, as this festive outing of his immersive sketch show proves. Inept inventor/salesman Brian Butterfield, here hawking his 'Christmas pizza', is a delight as ever, and impressions of Terry Wogan and David Attenborough veer dangerously close to genius.

A festive episode of a wildly underrated sketch show. Serafinowicz is a versatile actor and a terrifyingly good mimic, but the left-field TV parodies of his 2007 series were perhaps too weird for mass consumption: this is brighter, faster and straighter. There's the odd regrettably unsubtle lampoon (eg Terry Wogan as a hash fiend), but there's also a successful move into traditional sketches, plus joyously imaginative send-ups of Apple adverts and Planet Earth, and fan favourites such as enormous salesman Brian Butterfield, here hawking his comprehensive Christmas pizza. It's a torrent of kooky silliness, textured by Serafinowicz's powerful and slightly scary screen presence. When he's on form - as he often is here - he looks like a star in waiting.
