8. Jurassic Park - "An adventure 65 million years in the making."
Spielberg has built his career on rollicking adventures and his Dino-fest was no exception. This clever tagline does a great job of emphasising the scale of what is about to unfold and really plays up the epic nature of the movie at hand. This was a typically Spielbergian rollercoaster of a movie and nobody could pick fault with the 'adventure' part of the tagline. I should point out however that the Jurassic era was actually more like 145 million years ago, so on that level it's slightly incorrect. Unless of course that's just how long Richard Attenborough had spent trying to perfect that weird Scottish accent he abandons halfway through. I never noticed that as a kid. Go ahead and watch it again, when he's talking to Sam Neill in that trailer on the dig near the beginning of the movie he's doing a Scottish accent, then by the end of the film it's completely gone. Anyway, I'm distracted, the point remains, it's a great tagline which conjures up images of a prehistoric world before you've even seen a single shot of the film.
