Britain's Got Talent: Northern Ireland's Matt McCreary is a real high-flier
But the joke's on Simon Cowell as contestant feigns injury after fall from balcony
It is Simon Cowell's turn to fall for a Britain's Got Talent prank tonight when a fearless free-runner pretends to be injured after plunging from a balcony during a terrifying routine.
Cowell, who earlier in the week conned Amanda Holden into thinking she was being dumped from the show for Cheryl Fernandez-Versini, was left open-mouthed when 20-year-old Matt McCreary, from Belfast, leapt around the stage.
Viewers tuning in to tonight's show will see Cowell ask McCreary: "Oh my God, Matt are you really ok?" as he lies on the theatre floor after diving from a balcony.
The 20-year-old, who also leaps over show hosts Ant and Dec on stage, also impressed Amanda Holden, who told him: "We have never seen anything as brave and dangerous before."
But not everyone on the panel was won over, with David Walliams joking: "Jumping over two people who are that short isn't really such a big deal."
The 20-year-old Co Down man is hoping his appearance on the ITV show will help kick-start his career as a stuntman.
Matt teaches parkour and free-running in the T13 Urban Sports Park in Belfast, where he is sponsored by IronFit - the team who put The Fall actor Jamie Dornan (above right) through his paces on a visit home earlier this year.
"I do a lot of work with cross-community youth groups and personal lessons with martial arts fighters," Matt said.
Parkour and free-running is "using the urban environment or any obstacle you are given to move over it in whatever way you chose".
Prior to T13, the training fanatic worked in coffee shops for Domino's Pizza and doing odd jobs.
"I have always been really adventurous since I was kid," he said.
"I was always climbing trees and me, my brother and my dad have been to the top of every peak in Northern Ireland. He would take us to a different mountain every week.
"I love Bloody Bridge up in Newcastle. There is a big mile stretch of rock boulders over water. As a kid I would run ahead of everyone, jumping over all the rocks."
Matt said he hasn't caused himself any major injuries during his daring endeavours.
"Just bumps and cuts and scratches," he said. "The only thing I have broken is my thumb and that was at the gym.
"My main goal is become a stunt performer. I do a lot of acting and martial arts. I am doing a few wee internet adverts with Toyota and lots of student films."
Legendary martial artist, film director, producer and actor Jackie Chan is one of Matt's heroes.
Stephen Bell, co-founder of IronFit said: "We met Matt a year ago when he was pursuing parkour skills at T13, where IronFit is based. Everyone here is inspired by his human movement and it personifies what we teach. We've helped develop and support Matt in his free-running and parkour and we're really excited for what the future holds for his talent."
