The Pudsey movie was thrown into chaos when the Britain's Got Talent dog became ill on set, according to reports.
The Sun said that the dancing pooch, who won the show in 2012 with trainer Ashleigh, became ill after eating too many ham sandwiches.
Filming came to a halt and the Border Collie-Bichon Frise was rushed to a vet for x-rays.
A source told the newspaper: "Pudsey just wasn't being himself last Sunday and then started writhing around in agony.
"Producers had a fit as he's the star and the movie still has some way to go. He's in virtually every scene so production had to be shut down, costing thousands."
The source added: "It appeared he'd just been scoffing too much rich human food which didn't agree with him."
Britain's Got Talent judge David Walliams is set to voice the dog in the fictional film, Pudsey: The Movie.
