So if it's 60 feet behind you, you don't have much time left. Creatures in movies which move slower than the creatures they pursue must lose them appropriately. You run about 20 feet per second. A guy lumbering along with his knees locked will cover about three feet per second. Therefore, if he chases you for five minutes, he will be a mile away, and you can safely stop at a pub for a pint and a smoke, because it takes him about half an hour to cover a mile.
People love dinosaurs.
People love Spielberg. I suppose you know that the original is the fifth-highest grossing movie of all time in domestic box office, and did nearly a billion dollars worldwide. And that's just where it belongs. And it only rates that high because of voters under the age of 18, who rated it a more generous 5.8. Available in zillions of different DVD's, in combination with Juraissic or without it.
