The Generation Game's reboot with Mel Giedroyc and Sue Perkins has been cut to just two episodes.
Mel & Sue will host a revival of the series later this year, but two of the originally planned four episodes have been dropped.
A source told The Sun newspaper: “The BBC had announced four programmes, but when they saw what had been taped could only realistically air two.”
It's said the decision could cost the BBC as much as £400,000.
A spokesperson for the channel said: "During the production process it’s not unusual for a new series to change length as the format evolves, and we’ve got a brilliant show for audiences on BBC One this Spring.”
Previously hosted by the late Bruce Forsyth, the BBC says The (new) Generation Game combines elements everyone knows and loves from the original series, whilst being brought "up to date with a hilarious selection of brand new games and challenges for families of all ages to play in studio and enjoy watching at home".
Pairs of family members across generations will battle it out in a series of fun performance and task based games with the ultimate goal of facing the legendary conveyor belt, and taking home an array of fabulous prizes.
All the family pairs will start the show in the studio audience and only find out which game they’re playing when Mel and Sue get them from their seats. There’s no time for rehearsals in this gameshow, so anything could happen on the night.
Mel and Sue are joined by a panel of star judges, there to score our family pairs after each game and ultimately decide which pair faces the conveyor belt.
Furthermore, special celebrity guests will be getting involved in the action along the way.
Mel Giedroyc and Sue Perkins said of joining the show: “It’s a cuddly toy, it’s a toaster, it’s a circular power saw, no it’s MEL AND SUE DOING THE GENERATION GAME! We can’t believe it, we are so excited!”
