If, like me, you haven’t seen Jurassic Park in a long time, you may struggle initially with Hold On To Your Butts’ fidelity to its source material. Greater familiarity with the film is undoubtedly beneficial for appreciating its direct correspondences, the physical comedy dexterity and clever use of rudimentary props and foley to bring its blockbuster spectacle to life. But I swear that this wonderful spoof production from the New York-based Recent Cutbacks company also reminded me of scenes long forgotten, a remarkable achievement.

As the cast of two, Natalie Rich and Matt Zambrano do an incredible, highly involved and energetic job, cycling through the main human cast and dinosaurs with dizzying speed, slipping in and out of characters with little but the putting on of a pair of sunglasses or a backpack. Through their limber, expressive performances, a convincing, stomping Tyrannosaurus Rex is evoked with a cycle helmet and traffic cone, velociraptors with swimming goggles. The diamond in the show’s crown though is any chance either of them get to indulge in the rich luxuriance and weird, staccato phrasing of Jeff Goldblum’s dialogue, an opportunity they both seize with relish, although Rich also exquisitely captures Laura Dern’s semi-permanent pained grimace.

All the while, the duo are supplemented by Kelly Robinson on sound effects, visible stage right and engaged in a maelstrom of sound and fury. Lovingly sending up Steven Spielberg’s epic, while affectionately poking fun at its dafter plot points and excesses, Hold On To Your Butts is a tremendous amount of fun for younger teens and anyone upwards of that age.
