Behind the scenes of 'Walking With Dinosaurs', a show that features 18 life-size realistic animatronic dinosaurs

• We went behind the scenes of the "Walking With Dinosaurs" show.
• It is the closest that you will get to a real-life Tyrannosaurus Rex.
• Each dinosaur cost around $1 million to make.

Business Insider went behind the scenes of the "Walking With Dinosaurs" show, a live performance featuring 18 life-sized dinosaurs.

We saw how each of the huge, realistic animatronic dinosaurs is controlled, and it's quite a coordinated operation.

Bigger dinosaurs such as the Tyrannosaurus Rex are controlled by three operators; a driver who moves the dinosaur forwards and two voodoo operators who have control of the head, tail, eyes and sounds of the beast.

The smaller dinosaurs, such as the baby T-Rex and Velociraptors are controlled by performers inside the suit. Each suit weighs 40 kilograms, so much training and practice is needed before climbing into them.

"Walking With Dinosaurs" is currently touring Europe and tickets are available on their website.
