Jurassic Park at 30

Jurassic Park was released in US cinemas thirty years ago today. Michael Crichton basically took his sci-fi theme park disaster idea Westworld and replaced cowboys with dinosaurs, and Steven Spielberg made it more-or-less family friendly, playing up the appeal of the idea - yes, I want to go see live dinosaurs! - as well as the danger when it all goes wrong.

CG effects were just there, with each shot taking a long time to process so a lot of work done to make them all work, while puppets and costumes were used extensively as well.

And one of the best known effects shots is the water on the car dashboard, made by plucking an attached guitar strong.

I remember the trailer with the big reveal of the Brachiosaurus stopping halfway up their necks - teasing that the effect would probably work but not confirming it. (But I can’t actually find that clip now.)
