Images released of the forthcoming
series include dancers in all over body suits that cover their faces, a singing parrot
and a footballing dog.
The use of animals in eccentric
acts appears to have increased.
Ant McPartlin, who presents the show alongside Declan Donnelly, said that in the course of one day he was bitten by a dog, chased by a pig and shouted at by a contestant.
For the second year running the judges will make their decision in front of an arena
audience gathered in major audition cities.
McPartlin said: "The audience were really harsh
this year, especially in Glasgow. They were quite volatile
there with no patience."
Simon Cowell, one of the judges, said that he was hoping that a dog would win the show this year.
In 2008 Kate Nicholas, from Cheshire, and her dog Gin made the show's final which was eventually won by George Sampson, a young break dancer.
