Production crews will use Blue or Green Screens to help create the illusion that people or objects you’re watching on TV or at the movies can do amazing things - fly, run or even jumping over tall buildings!
Most wrestling is 'predetermined' (the wrestlers know who is going to win before they get to the ring) and choreographed (planned and moves worked out before, a bit like a dance routine).
ALL wrestlers undergo years of training and learn how to wrestle, take falls properly and look after themselves. Never ever try what wrestlers do in the ring at home, school or anywhere else... you may end up getting seriously injured or worse.
The wrestler that Mister Smooth has a grapple with is Robert Bruce who was the commonwealth wrestling champion in the 1970's and once fought for the world title. His finishing move was called the 'caber toss'.
By adding sound effects to things, TV and Film crews can make things appear differently to what they really are..... (and sound ten times worse than they really were)
