Based on the award-winning BBC TV series Walking With Dinosaurs, The Arena Spectacular has won widespread acclaim during two sell-out tours in Australia and America and promises to be one of the most groundbreaking shows ever seen in Britain.
The show has been seen by two million Americans, including Brad Pitt and Angelina Jolie.
Top billing goes to a terrifying 20ft Tyrannosaurus rex which, in a dramatic climax, tries to protect her baby from predators.
The cast also includes an allosaurus, a torosaurus and a utahraptor.The largest, the brachiosaurus, is 36ft tall and 56ft from nose to tail.
Featuring 15 realistic, snarling and roaring animatronic dinosaurs, the show will take over the O2 arena in London for five nights from August 5-9 followed by six nights at Wembley Arena from August 26-31.
Tim Haines, creator and producer of the original BBC series, worked on the live show as a consultant.
He said: 'At its core, the spectacular manages to do what the TV series did so successfully, which is to make people imagine they are looking at real dinosaurs.'
The beasts are operated by 'voodoo puppetry' which involves a backstage team manipulating miniature versions with the same range of movements as the life-sized counterparts.
Movements of the puppets are replicated on stage.
Newsweek hailed it as 'that rare entertainment beast that parents and kids can enjoy together'. Variety said the dinosaurs are 'stunning and faultlessly nimble'.
