Jonathan Creek and One Foot in the Grave creator David Renwick has revealed that he "walked off" a new ITV series one month into pre-production.

Renwick's six-part comedy Ergo would have focused on the relationship between a young man and his mother-in-law, but the writer revealed that he departed the project after becoming "disenchanted with the notes coming down".

"I walked off a month into pre-production," he explained. "I thought, this is it - life's too short."

Renwick explained that while he offered ITV the chance to buy and rewrite his original scripts, the channel ultimately decided to "junk [the series] altogether".

"I did actually offer to sell them the scripts. because we were a month into pre-production - the director was on board, we'd been auditioning, locations were being scouted and money had been spent by ITV Studios," he said.

The award-winning writer was speaking at a press event for a new Jonathan Creek special, expected to air on BBC One this Easter.

A further three Creek episodes will follow the special in 2014, series star Alan Davies revealed yesterday.
