Simon Cowell, David Walliams, Alesha Dixon and Amanda Holden can pick one act from the losing semi-finalists to join the top 10 as a wildcard and hand them a second chance to battle for the £500,000 grand prize.
But who should be given the free pass to the final? Reality Bites has picked out its favourite acts from the also-rans who didn't quite make the cut first time around.
A man with a pan on his head doing Dalek impressions. What more explanation do you need? Just for the fact we might get another shot of multi-millionaire Simon Cowell sat with some kitchenware balanced on his fuzzy flat-top means Martyn gets our vote.
A child singer who doesn't come across as precocious. A child singer who will shrug her shoulders and move on rather than burst into tears if she loses. Lauren Thalia is remarkably grounded and also remarkably talented. She was unlucky to get lumped in the strongest semi-final on day one.
BGT may have lacked a bit of fizz and fun this year, but Mr Zip did his fair share to keep us entertained. His 'Where My Keys, Where My Phone' ditty is the most evil of catchy earworms, but damn it, we want to hear it again.
A barmy German singing while dressed in an all-gold metallic Power Rangers-esque costume. Dennis Egel was the epitome of BGT nuttiness and the show is less fun without him in it.
We're still not entirely sure what Billy George's act is (something to do with spinning in a giant hula hoop), but for his torso alone, the readers of Gay Spy should be keeping their fingers crossed that Billy gets a second chance.
Another act which was unlucky to be part of the strong first semi-final lineup, The Mend were beaten by Pudsey the dog first time around. However, these rough-around-the-edges Mancunians showed plenty of promise in their two performances. We all know how much Cowell likes a boyband, so they are probably the favourites to get the nod.
Twist & Pulse Dance Company
Their mentors Twist & Pulse finished runners-up, so they know what the judges are looking for, but they were edged out in the public vote during the semi-finals. The strongest of all the dance troupes this year, T&PDC are more than worthy finalists if the judges want some body-popping moves in the final.
