Britain's Got Talent viewers angry as magicians' tricks 'exposed'

The Haunting and PC Dave Wardell had unfortunate blunders, which were spotted eagle-eyed viewers during the live show.

Britain’s Got Talent viewers spotted blunders and bloopers in the first live show, which exposed the tricks and secrets of magic acts The Haunting and PC Dave Wardell and Finn.

The Haunting’s act involved taking judge Amanda Holden backstage and a ‘supernatural’ swap between illusionist Elizabeth and the spirit Agatha.

However, the switch was exposed by the camera-work from the BGT production team, which meant that they could see Elizabeth hiding round the corner on the stairs as Amanda was walking up.

"Did anyone else see the other girl coming out of the stairs to take over from 'Agatha'?" said a viewer on Twitter.

Another viewer added: "The haunting wasn't even real, you could see the woman change on the stairs!"

The blunder was overshadowed by Amanda Holden’s shocked reaction, when she used the F-word, screaming in response to the chilling trick.

Holden and presenters Ant and Dec apologised to viewers for the bad language, which aired before 9pm.Another error came during dog act Dave and Finn’s psychic predictions, as they unveiled a pre-recorded video featuring answers that the judges gave on the love show.

However, viewers spotted the error made by the policeman, who could be seen switching the six letters 'chosen' at random by the judges.
