Quiet, all of you. You're approaching the tyrannosaur paddock... How the hell they manage to fit a fully fledged T-Rex into the confines of Waterloo Vaults is a secret reserved for the lucky audiences of Jurassic Park.

(And it's not one of those plastic litter-pickers with a dino head that were all the rage in the Nineties. I remember being terrorised by a boy at a birthday party with one of those as a child, so I was pleased not to have to relive the trauma...)

No, one of the great things about this send-up of Spielberg's blockbuster on stage is the inventive lengths gone to in order to recreate the pioneering animatronics (with not a hint of machinery in sight).

A new one-hour show from theatre makers SuperBolt (epic name, I know), it's playful, funny and endearing in equal measure.

Expect slick timing, characters you can root for, a video game-style battle with a dino and some brilliant performances from the cast of three.

There are a few moments which you suspect are for the hardcore Park fans but even without minute-by-minute knowledge of the film, it's vastly enjoyable.

Loosely cast in the Edinburgh Fringe-worn mould of lovingly parodied classics, like Casablanca: The Gin Joint Cut and the one-man Star Wars show, let's hope this gets a Scottish outing of its own.

Jurassic Park finishes this week at the Vault Festival. Performances on Saturday and Sunday only at 8.30pm, with weekend matinées at 4pm.
