Britain's Got Talent: The Champions act Deadly Games have promised their "best and the most dangerous performance" this weekend.
BGT's All Stars spin-off is back on Saturday night with its second heat.
The series is welcoming back acts from the past 13 years of Britain's Got Talent to compete against one another, as well as acts from across the world.
One of the contestants on this weekend's show are daredevil duo, Alfredo and Aleksandra, known as Deadly Games.
The act first rose to fame on America's Got Talent where Alfredo's performances saw him throwing knifes and firing crossbow bolts at his partner.
This weekend they'll bring their act to the BGT stage with Alfredo declaring: "This is the best and the most dangerous performance we have put together, ever."
Ahead of Saturday's show, he told The Sun newspaper: "If I miss, she could die."
He added: "I don't want to give too much away but basically we are going to use Anna's flexibility and I am going to shoot arrows very close to her body. That's all I can say."
Despite the risks, Aleksandra said she was "never scared" and "so confident" in Alfredo not to hit her.
Other acts on BGT: The Champions this weekend include the first comedian to ever win BGT, Lost Voice Guy, along with Alesha’s golden buzzer from series 11, dance group Mersey Girls and series 5 winner, singer Jai McDowall.
We also welcome back choir 100 Voices of Gospel, acrobatic duo Gao Lin & Liu Xin Italy's Got Talent's Antonio Sorgentone and British ventriloquist Paul Zerdin who previously won the American show, plus German dog act Alexa Lauenburger.
Two more acts will make it through, joining last week's first heat winners, Ukrainian sand performance artist Kseniya Simonova and daredevil duo Bello and Annaliese Nock.
Britain's Got Talent 2019 airs at 8:30PM on ITV Saturday night.
