The talented French stars wowed the judges at the weekend with their fight routine, winning a spot in the next round.
Alesha raved: “From the beginning it was so aggressive, it was like an action film and it just got better and better. It was like Mission Impossible.”
She added: “I’m really struggling to look at your faces just now so I think we better vote!”
Speaking after their successful audition, the boys revealed: “In front of the judges we performed a human stunt show and acrobatics show – a gathering between comedy, martial arts and stunt.
“Alesha says our show is like an action movie so for us it’s a big honour to hear that.”
The group have been performing together for 10 years, acting as stunt doubles in movies, but would love their own motion picture.
They revealed: “Our dream is to produce and release our own action movie with the team.
"Amanda and Alesha would be first on the red carpet for that release."
We'll see if Cascade made the live shows in a two weeks' time!
