Roughly, it's estimated that Doctor Who costs £770,000 an episode. So does the Telegraph really believe that the three-minute Radio One ad cost £700,000?
The advert is estimated to have cost up to £700,000 – for facilities, crew, animal hire, costumes, special effects and production time
Really? says who?
– according to advertising sources.
Oh. "Advertising sources". You should have asked a bloke down the pub, Telegraph. Blokes down the pub are great at estimating the costs of producing something that, by definition, they haven't seen.
