This is as fluffy as the trim on Santa's costume and as daft as the idea that an overweight middle-aged man could ever squeeze down your chimney. But let's not quibble, because this one-off comedy drama, the latest spin-off from Christmas Lights, reunites the popular Robson Green and Mark Benton as competitive brothers-in-law.

This time they're taking part in an international Santa competition in Lithuania. By the time they've had a go at the likes of turkey bowling and mince pie munching, there's barely time to get home to their families for Christmas. The storyline is thinner than gravy in the Scrooge household, so just think of this as a vehicle for Green and Benton to be lovable chappies against a festive backdrop of Santas and snow.

You know what to expect when Robson Green and Mark Benton get together for one of these shamelessly lightweight comedy-dramas - especially when, as was the case when they first paired up to play these warring brothers-in-law Colin and Howie, the storyline is centred on Christmas.

This latest outing finds them heading off to Lithuania (well, why not?), where Howie has been asked to represent England at the World Santa Championships - the snag being that he happens to hate Christmas and all it stands for. Colin, on the other hand, still believes it's a magical time of year, and is more than a little aggrieved that he hasn't been offered the role himself.

Edge Falls, your out of town retail Mecca, the comic brain child of Paul Barnhill and Neil Warhurst, returns. Mark Benton plays Mick, hapless head of security. Frances Barber plays the ingenious promotions manager Sonya, raising a giant pink inflatable love heart over the shops to bring in the pink pound. And all the staff has to be gay friendly too, but only to friendly gays (nothing ostentatious). We're gay for the day, says Sonya, before she spots what she thinks is a bit of hanky panky in the carpark. The spoof commercials are a treat, though.

ITV to air Harry Hill soap spoof

Hill will play a pub landlord called Arthur Buttons in the new show, and has made a pilot co-starring Liza Tarbuck (as his mum), Mark Benton and Kate Robbins. It has now been commissioned for a series.

The BBC describes Edge Falls - written by Paul Barnhill and Neil Warhurst, and starring Mark Benton and Sarah Lancashire - as a five-part comedy. But the line between that and tragedy has rarely seemed so thin.
